$\frac{1}{1+\frac{x^2}{y^2}}\frac{d}{dx}\left(\frac{x}{y}\right)$

Learn how to solve special products problems step by step online. Find the derivative of arctan((x/y)). Taking the derivative of arctangent. The derivative of a function multiplied by a constant (\frac{1}{y}) is equal to the constant times the derivative of the function. The derivative of the linear function is equal to 1. Multiplying fractions \frac{1}{1+\frac{x^2}{y^2}} \times \frac{1}{y}.
