TRUE/FALSE QUESTION: Iplicit differentiation
TRUE/FALSE QUESTION: Iplicit differentiation can be used to find
slope, dy/dx, at any point (a,b,) on the curve x^2 + y^2 = r^2, as 2xdx +2ydy = 0, or dy/dx = -x/y = -a/b without having to express y= plus/minus sqrt (r^2 -x^2) and then differentiating y to get dy/dx.
