Solution 12216: Graph of nDer(sin(x)) on Graphing Calculators is Different in Degrees and Radians.

Why is the graph of nDer(sin(x)) different in degrees and radians?

The graph is different in degrees and radians because the derivative is different. In radians, the derivative of sin(x) is cos(x). In degree mode, the derivative of sin(x) is (p*cos(x))/180. This effectively returns a radian result for the derivative.
