[QUOTE="redleg1013, post: 1986594, member: 49994"] It depends. If the slope is a straight line between two points then cos will hold up. If the slope is concave then the angle is an average, then you'll have to figure cos against an average rate of change [f(b)-f(a)]/(b-a) to be close, or go through the whole cosine of the instantaneous rate of change maths if you want to be precise.
