Find the rate of change of the distance between the origin and a moving point on the graph of
y = x^2 + 1 It dx/Dr = 2 cm/second
I proceeded taking the implicit derivative of the given function to find dy/dt.
dy/dt = 2x* dx/dt
dy/dt = 2x* (2) and the I plugged x = 0 from the origin value for x.
dy/dt = 2(0)* (0)
dy/dt = 0...My Answer.
My Answer is zero and the book's answer is a crazy rational function.
Can someone answer this question?
