Well, checking again my calculations I can ensure that I'm getting a little difference between what the component calculates and what I calculate with a calculator. The difference is of 0.026 wich is almost nothing, but I would like to reduce it a little more.
I'm using dobule floating point variables but it seems to make no difference. Do you guys know why I have this difference in the numbers? Is it because I'm working in radians with the component, and with the calculator I'm using degrees?
