[QUOTE="Nusc, post: 6065478, member: 30741"] If one rotates a tangent plane on a curved surface, this point can be expressed as follows: x' = x cos(theta) - y sin(theta) y' = x sin(theta) + y cos(theta) One solves for x and y and computes based on the deviation of the deviation. My question is: would the answer differ if you choose a different point say: x' = x cos(theta) + y sin(theta) y' = - x sin(theta) + y cos(theta) note the negative sign. [/QUOTE]
