Final answer to the problem
Step-by-step Solution
Learn how to solve factor problems step by step online. Find the derivative of xarctan(x). Apply the product rule for differentiation: (f\cdot g)'=f'\cdot g+f\cdot g', where f=x and g=\arctan\left(x\right). The derivative of the linear function is equal to 1. Taking the derivative of arctangent. The derivative of the linear function is equal to 1.
