$\frac{d}{dx}\left(\frac{\pi}{2}-\arctan\left(x\right)\right)$
Learn how to solve sum rule of differentiation problems step by step online. Find the derivative d/dx(pi/2-arctan(x)) using the sum rule. Simplifying. The derivative of a sum of two or more functions is the sum of the derivatives of each function. The derivative of the constant function (\frac{\pi}{2}) is equal to zero. The derivative of a function multiplied by a constant is equal to the constant times the derivative of the function.
