I am working on the task in which I have to make a circle which is having n number of equal parts. I am provided with centre and radius of the circle which is (0,0) and 4 respectively. To achieve this task, I have written below code, However, after running this code, I got output like below which does not

Sympy calculation on tan function
I have a problem when simplifying a symbolic expression in sympy when having a trigonometric function and a complex exponent, namely I just assumed a different definition of tan function, and I have a weird thing going on. So I do: Symbolic variable sym.simplify(test2) is equal to -tan(a) and normaly test1 variable should be equal to 0, however when I
curve fitting sine to the power of python
I want to fit a signal into a cos or sine function: reference signal: And this signal must fit into model: By doing: I am getting: params a = 11.9; b = 0.97 and n=1 This doesn’t match at all… Answer putting these suggestions together gives the following: which recovers your parameters. the bounds enforces positivity, while the p0 gives
Calculating angles between line segments (Python) with math.atan2
I am working on a spatial analysis problem and part of this workflow is to calculate the angle between connected line segments. Each line segment is composed of only two points, and each point has a pair of XY coordinates (Cartesian). Here is the image from GeoGebra. I am always interested in getting a positive angle in 0 to 180
How to calculate the angle between a line and the horizontal axis?
In a programming language (Python, C#, etc) I need to determine how to calculate the angle between a line and the horizontal axis? I think an image describes best what I want: Given (P1x,P1y) and (P2x,P2y) what is the best way to calculate this angle? The origin is in the topleft and only the positive quadrant is used.
