The Solution Rating System

|
With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.
Your Input Matters If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support. Thank you! |

Still trying to get a part of a programme working following up this question http://www.experts-exchang
I'm having a problem seperating the circle into segments. I'm wanting to draw a line every 3.6 degrees. Or even better draw from 0 on left to 100 on right (image 1) with appropriate 100 segment degrees inbetween.
My problem is that when I set theta to different values in my code (attached) I get different angles drawn!
Code at the moment draws all the lines on top of each other as this was how I noticed that it was drawing the lines at the correct degree segments!
Any suggestions on whats going on here? Or perhaps how once overcome this problem how I can start to work out my desired result!
p.s. Sorry if in wrong area!
Thanks
James
