Learn how to solve product rule of differentiation problems step by step online. Find the derivative using the product rule (d/dx)(xtan(y)). The derivative of a function multiplied by a constant (\tan\left(y\right)) is equal to the constant times the derivative of the function. The derivative of the linear function is equal to 1. Any expression multiplied by 1 is equal to itself.
