Final answer to the problem
Step-by-step Solution
Learn how to solve sum rule of differentiation problems step by step online. Find the implicit derivative d/dx(x^2+arctan(y)=y-1). Apply implicit differentiation by taking the derivative of both sides of the equation with respect to the differentiation variable. The derivative of a sum of two or more functions is the sum of the derivatives of each function. The derivative of a sum of two or more functions is the sum of the derivatives of each function. The power rule for differentiation states that if n is a real number and f(x) = x^n, then f'(x) = nx^{n-1}.
