Using Sin-1 or inverse sin in python

Question

Here is my code:

# point of intersection between opposite and hypotenuse

x,y  =    pygame.mouse.get_pos()


# using formula for length of line

lenline1 = (x-x)         


        

Answer 1

Don't bother with the k computation, its meaningless.

j = math.asin(PQ)

However, this only works for right-angled triangles and you have to appropriate side lengths in the right places. In general this will not work and you need to use the dot product method.
