Learn how to solve constant rule for differentiation problems step by step online. Find the derivative of 2*pir using the constant rule. Simplifying. Apply the product rule for differentiation: (f\cdot g)'=f'\cdot g+f\cdot g', where f=. The derivative of the constant function (2\pi ) is equal to zero. The derivative of the constant function (r) is equal to zero.
