Hei!

I am trying to compute the following function

function [x,y] = f(z) x=cos(z)*2; y=sin(z)*2; end

The answer I get in the end (z=50) is x=-1.904825 and y=-0.60962. But this answer is not correct.

Can somebody tell me where I did mistake?

cos and sin are assuming input in radians. Is that what z is in? If it is in degrees, use cosd and sind instead.

Ok. I guess this is a reason why I get "wrong" answer. My input is in degrees.

Thank you, Sir
