I have computer program I am writing where I need to calculate the position of a point(called P) when rotated around another point.
I am attempting to come up with a general function/formula I can use to calculate this point P but my Maths is a little weak & I cannot identify what arc/tangent formula I am meant to use.
Can you assist me to come up with a formula I can use to calculate point P for rotations that can be both positive & negative?
I know how to calulate the length of the line between points (14,446) & (226,496) but not how to calculate the blue point x,y position - BTW: the length of this line is the same as the line between the blue point & (14,446)
len = sqrt( (496-446)^2 + (226-14)^2 ); = 227.56;
