Dear experts,
I am planning to pursue a Masters in Financial from one of the UK universities.
Given that the H1B (Work-visa) becoming tough to get I am not too inclined to apply to US universities. My educational background
1. High school-commerce (no mathematics)
2. Bachelors - commerce (no mathematics)
3. Chartered Account - (no mathematics)
4. Costs and Works Accountig (no mathematics)
5. CFA (https://www.cfainstitute.org)-Some basic risk related maths Experience: Telecom industry/Amex cards/Retail and commercial banks Recent Profile: Prudential reporting to the regulators/capital and liquidity stress testing Previous industry: Risk management consulting in Big 4 firm (EY, PWC, KPMG, Deloitte) My daily routine: Study all the hours (24,7,365). I have tutors who come to my place and teach me the subjects. I have another 1.5 yrs I can give my complete attention to studies (does not include university time). Please do not see it as my arrogance. This is the level of effort and dedication I can /willing to put.

I am planning to Masters of Science in Financial Engineering (FE).
I do not have math background at all. So I have resigned from my job and now doing mathematics.
I am unable to determine whether the expertise in the following list of topics is a prerequisite for FE (See below list). I generally consult https://quantnet.com/ for details. But i am not getting any clue for the below topics.
I am clear about the rest of the topics (At high level which are required) as a pre-requisite for FE.
When i say expertise, I mean an indepth subject knowledge. By mean knowledge i mean knowing/learning to the extent it is needed to complete another topic.
Kindly guide me.

I am wondering about exactly how to convert radians to a reference angle in terms of pi. I was given the following problems:
theta=4, theta=7, theta=11, and theta=-10.
I was told to find the quadrant, which was easy, and then the reference angle in terms of pi. I understand that the first one is 4-pi because pi represents 180 degrees so you must subtract 4 radians from 180 degrees to get the reference angle of it, 4-pi. However, the second one is in quadrant one, meaning you would not have to do any translations. but how would you figure out what it is in terms of pi? Also, the angle for theta=11 is more than 360 degrees. Knowing that it is quadrant 4 (11 times 180/pi), how do I figure out how to find out it in terms of pi? Also, what when theta is negative? Do you change the way you look at the graph or simply add a negative sign to the answer?
- Additionally, after I find out what it is in terms of pi, how do I get the same reference angle in the first quadrant in terms of pi?
I like to understand my daily electronics consumption. I understand an average desktop computer has a power usage of between 80 and 250 watts hour of "active" use, depending on graphics cards and additional peripherals. A laptop is 50 to 100 W/hour. In stand-by mode the power consumption of both a desktop and a laptop falls to about a third. The cost to the University to operate a typical computer and monitor workstation (130 watts @ 11c kW/h) for 24 hours per day, 7 days per week, 365 days per year, is $129.73. It appears from electric bill I am 10 kW/h. My energy use to date start from 2/22 is 207.31 kWh. I use my laptop and dual monitors pretty frequently for 7 hours a day / 5 days a week. Can someone explain the math here?
I need help writing a root finding problem using Newton's Method for the following equation:
y = sin(x) − 0.15x + 1.5
I want to use a tolerance of 1.0e-4 and double precision to find all roots (5 total) of the equation.
I would like some assistance on how to go about writing the derivative function to better understand the main program too. Any help is appreciated.
In describing a black hole and its immense tidal gravity, how do you describe the forces acting on a body as it approaches the singularity?
Here is the phrase I am trying to understand:
"This creates a tension gradient across the object parallel to any radii colinear with both the object's center and the singularity."
I have an array (raw_acceleration) of 1600 elements acquired every 10 seconds at 160Hz from a sensor.
i use this array to calculate the fft and the Power Spectral Density and it works very well:
I obtain this plot:
As you can see, I obtain four peaks centered around four different frequencies.
I would like to have a Matlab code which is able to automatically find these four maximum peaks and their frequency.
At the moment, I always need to plot the graph and manually detect the maximum peak and its frequency.
Is there any way to do this by code?
I hope you an help me.
I am learning the graphing of trigonometric function on my notes (not using any calculator).
I have come across the following format of the sin function
y= A.Sin(bx-c)+D
I am trying to see if there could be a trigonometry function like y= A.Sin(-bx-c)+D
That is the number of cycles being negative (-b instead of +b).
Kindly help me with a source which gives such complex problems and also provides solution. Since my practice till now has been on sin trigonometry function, I would like to see a few examples on sin function.
In trigonometry functions, we have y=sin-theta and y=a.sin (3.theta + 30 degrees) + 60 degrees
I understand that when y=sinx we use the unit circle with radius of 1unit to explain radian/amplitude.
I am trying to under the following concepts of amplitude, phase shift and vertical shift. I understand the concept of period for trigonometric functions.
Now is there a sequence of videos or notes which will help me understand these concepts. Not just the calculations but also the implications of unit circle and on the trigonometry functions. My struggle is not just to crunch numbers but also to understand the concepts how the numbers are impacting the trigonometric functions.
I am learning trigonometry and derivatives.
In this regard I am looking for a software which can draw the graph for the quadratic/third degree equations.
I am home user so looking for an affordable software graphing solution.
Hey all I am in need of some help with determines what box I need to place a given image into depending on that images ratio (image width / image height) to the box areas Aspect Ratio (box width / box height).
The code below is what I currently have that I am using to determine this (which does not work):
public static Dictionary<string, List<double>> sizeOfPhotoBoxes = new Dictionary<string, List<double>>()
{/*
[Width]
| [Height]
| | [Aspact Ratio]
↓ ↓ ↓
KEY: VALUE(s): [1] [2] [3]*/
{ "box1", new List<double> {357, 272, 1.31} },
{ "box2", new List<double> {357, 272, 1.31 } },
{ "box3", new List<double> {365, 460, 0.79 } },
{ "box4", new List<double> {365, 265, 1.38 } },
{ "box5", new List<double> {715, 455, 1.57 } },
{ "box6", new List<double> {360, 465, 0.77 } },
{ "box7", new List<double> {360, 465, 0.77 } },
{ "box8", new List<double> {360, 465, 0.77 } },
{ "box9", new List<double> {540, 290, 1.86 } },
{ "box10", new List<double> {540, 290, 1.86 } }
};
double RA = (double)item.images[0].width / item.images[0].height;
foreach (var AR in sizeOfPhotoBoxes)
{
if (AR.Value[2] >= RA && AR.Value[2] <= RA)
{
System.Diagnostics.Debug.WriteLine("found");
}
}
So what my goal is is to get the current image I am wanting to place into a box and get its width and height and from that determine the best box to place it in so that it will show the image:
- Without black borders on either the left/right or top/bottom (or both).
- Not chop off the important areas of the image (mostly the middle section moving out).
I have decided to use Magick.NET in order to ease the pain of doing something like this from scratch. So when I determine what box I will be placing the image into then I can use the Magick.NET to crop it using:
I would like to distribute the difference between the weekly labor target G2 and the weekly hours of operation I2 in even 0.25 chunks. The difference between G2 and I2 is in J2. If you multiply J2 by four you can see that I have 82 0.25 hour chunks of time available to distribute. How can I distribute those 82 chunks based on the needs represented by the ticket counts (workload) represented in column F. It's okay for some rows to be blank as long as I don't exceed the 82 chunks of time available and distribute the 0.25 hours to the intervals where the needs are highest.
I have tried distributing the labor based on a ratio defined by F/G but that often results in uneven labor or labor that is blowing the budget available. Example_LaborDistribution.xlsx
I'd like to write a Lambda function that fetches a (1) CloudWatch Metric (that is already being monitored at every 5 minutes), (2) divides that value by 300 seconds and (3) pushes to CloudWatch as a Custom Metric.
The CloudWatch metrics already being monitored are "Volume Read Ops" and "Volume Write Ops" on a could different active EBS volumes.
I have no every on using Java or Python for this.
Thanks for your help or pointing me in the right direction.
I have a set of seven parameters which are numerical values (i.e. current readings, pitch, roll and yaw angles, acceleration, etc..) and I use them to classify a vehicle behavior.
For example, if:
What is the best way to implement this kind of classification in Matlab?
Should I use a simple neural network? Or a classification method like SVM?
Is there any tutorial or example?
I have a set of data where each set of parameters is related to a specific behavior, so I can use this to train my model.
