Aim: Product/Quotient & Higher Order Derivatives Course: Calculus The Product Rule The derivative of the product of two differentiable functions f and g is itself differentiable. The derivative of fg is the first function times the derivative of the second plus the second function times the derivative of the first. Find the derivative of h(x) = (3x – 2x 2 )(5 + 4x) = -24x 2 + 4x + 15 first derivative of second second derivative of first

Aim: Product/Quotient & Higher Order Derivatives Course: Calculus The Quotient Rule The derivative of the quotient of two differentiable functions f and g is itself differentiable at all values of x for which g(x)  0. The derivative of f/g is given by the denominator times the derivative of the numerator minus the numerator time the derivative of the denominator, all divided by the square of the denominator.

Aim: Product/Quotient & Higher Order Derivatives Course: Calculus Model Problem Because the moon has no atmosphere, a falling object on the moon encounters no air resistance. In 1971, astronaut David Scott demonstrated that a feather and a hammer fall at the same rate on the moon. The position function for each of these falling objects is given by s(t) = -0.81t where s(t) is the height in meters and t is the time in seconds. What is the ratio of the earth’s gravitational force to the moon’s?

Aim: Product/Quotient & Higher Order Derivatives Course: Calculus Model Problem s(t) = -0.81t Position Function s’(t) = v(t) = -1.62t Velocity Function s’’(t) = v’(t) = a(t) = Acceleration Function Acceleration due to gravity on the moon is meters per second per second. Acceleration due to gravity on earth is -9.8 meters per second per second.
