i have arccosunus from vectors x and y = I have tangential to the x and y vectors ( between -pi/2 and pi/2)
now maybe some one ( mayby mr Brian Barker) know the math algorithm to generate correctly tangential ( from ex sinusoids , left or right turning spiral, circle starting from left or right side etc), (mayby mr Brian Barker could make informatin about genearating tangential from mach3 tangential control fun ). Thank you Arek
