Use Electric shower curtains or just regular shower curtains as an example.
A followup question will add depth and length.
I just thought a shower curtain was a good example because it is height is clear (and there is no depth).
Dont use a door because there is depth and that would confuse me because there is no such thing as a flat door. But there is a flat shower curtain.
i'm looking for a compact (say 3ft x 2ft x 0.5ft) diesel or gasoline
quiet generator that could power the equipment in my house
(mostly TV, ceiling fan, lights that use 220-240V of 20-50Amp).
I guess air-conditioners will require much higher voltage/amperes
so will leave it out.
The last 1 year, I've got 7 burnt LED drivers (4W-24W) from unbranded (made in
China) & one even cause total power trip in the house : url above is one of them.
So far the LED lights are Ok, it's only the drivers. A contractor recommends
OSRAM. Would the following driver support all my drivers (that ranges from
4-24W) as it states 2-30W : I plan to replace all of them with reliable one:
A lawyer advised me and my spouse to write separate wills :
as the will is charged at a fee per will, I'm trying to establish if this is a general
practice out there & the reasons for it : if it's one joint will, it will be charged
for one will's fee.
Reason was the lawyer wants to customize it to meet our special-needs
(intellectually disabled who can't live on his own) kid but by making the
wills separate, I'm curious how this helps
Which industries use the "end of period" and "beginning of period" options in the PMT, FV, PV and other financial functions.
When I've taken out a personal loan at the bank, I was never asked "Would you like to pay at the end of the month? or would you like to pay at the beginning of the month?"
Which types of transactions? Is it non-USA entities? Is it real estate? Asset-based loans?
Can anyone point to an article, blog post, or video that discusses who uses the last option in these financial functions.
Hello Experts,
This is a math type of question. If I have a set of data for 100 people that falls into four income brackets, but one of the groups is 'No Income Data', what is the method for calculating (projecting) the income bracket for the 15 people with 'No Data' based on the percent/totals of the 3 groups that do have data. For instance, if I have:
25 people with an income less than $15,000 (25%)
50 people with an income $15,000 - $25,000 (50%)
10 people with an income greater than $25,000 (10%)
15 people with no income data (15%)
Without getting side-tracked by arguments of whether 0.9 recurring can ever equal 1, is there an accepted mathematical expression for the difference between 0.9r and 1?
I am considering whether the starting position for the pattern vis-a-vis the searched text, (i.e. the LAST CHARACTER of the pattern be aligned) ought to initially coincide with the first appearance of that LAST CHARACTER in the searched Text, *provided that appearance is equal to or more than the length of the Pattern*, since otherwise the index would have occurred too early in the sequence to be valid.
Consider this illustration from the B-M paper :
The B-M algo would 'mismatch' the final T from the 'pat' with the F from the 'string', and move the pattern past the F, to align the A with the I. Whereas the first contending T in the pattern and the string is at index 17 in the string, rather than the standing comparison being done at index 7.
I am preparing for Financial Engineering/stochastic calculus.
In the high-school level books I am referring to, the 'application of derivatives chapter' covering:
errors and approximations
Geometrical interpretation of the derivative
(normal/subtangent)
Lenth of tangent, normal, subtangent and subnormal
Angles between two curves and condition for orthogonality of curves
Derivative as a rate of change
Rolle's Theorem and Lagrange's theorem
Increasing and decreasing function
Global extreme and local extreme value
First derivative test/second derivative
Maxima and minima
I guess the above topics are explained with a view that students will further pursue engineering background.
CAn any of the experts please recommend if there is any book which focuses the application of the derivatives for those pursuing stochastic calculus or financial engineering.

I am doing the heavy lifting for Financial Engineering. As I am beginner in the Mathematics.
Can anyone please help me understand if the below book is good for gaining good understanding to the extent required for Financial Engineering or Stochastic Calculus? Or will this be an overdose.
I am not sure if this book was recommended to me by some expert here or I happened to collect this information from some external source.
Kindly advice.

I have now started classes for Financial Engineering.
I am not clear about the breadth /depth of topics in Vector Algebra required for Financial Engineering. I understand vectors also include vector spaces, vector matrix and vector calculus.
I have the following list of topics under Vector from high-school.
Can anyone please highlight which of these topics are required for Financial Engineering. Alternatively, if any of the experts have a list or an url which identifies the topics, please forward me.
I have done search in quantnet and other google results but could not get any clarity.

What is a Jeffrey fluid or a Jeffery flow or Jeffrey fluid flow or whatever. This is part of an assignment and try as I may, I cannot find what this is.
I have one problem with my circuit . I am trying to create an oscillator with dc current because I need an external clock for an application . I have connected a capacitor of 480 μF in series with the 5v pin . I have also connected an 2.2 Ohm resistor in series with my capacitor and the capacitor is connected to a digital pin .The digital pin is set programmatically to input.The time for the capacitor to be charged is :
V^2 /R *t = 1/2 C*V^2 so the formula takes the form of 1/R*t = 1/2 C => t = 1/2RC
Here's my code:void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
pinMode(8,INPUT);
}
void loop() {
// put your main code here, to run repeatedly:
From my long-list of several questions I have been posting, this is yet another one.
In my game to get ready for stochastic calculus for Financial Engineering, I am engaging a lecturer for Real analysis.
Now can i request any of the experts to list me the details of the topics in the Real analysis required to cover Stochastic calculus. Also if you can indicate which of these require a mastery, so that I can handle Stochastic calculus reasonably well.
The purpose of this question is, I am not sure if the lecturer will have the focus/background of Financial Engineering.
I want to study learn Stochastic calculus with good level of understanding.
As we speak I have to covered Trigonometry functions, inverse, triangle (properties) and hyperbola.
Can any of the experts comment if stochastic calculus requires very good knowledge and depth of Trigonometry. If it is not required then I can focus on other areas required for stochastic calculus.
