Its been a while since I've done any type of calculus. So here we go. Vectors is this scenario represent cords, which will translate in a vector in future calulations For the purposes of this calculation, Vectors only use (x, y). Vector 1 originates from pivot (0,0) and is of constant length X. Vector 2 is the result of Vector 1 pivoting by angle A and what I need is the formulas for calculating the new position of Vector 2 using the constant length X. Many thanks.
