$\frac{d}{dx}\left(\frac{5}{8x^3}+2\cos\left(x\right)\right)$
Learn how to solve one-variable linear equations problems step by step online. Find the derivative d/dx(5/((2x)^3)+2cos(x)) using the sum rule. The power of a product is equal to the product of it's factors raised to the same power. The derivative of a sum of two or more functions is the sum of the derivatives of each function. Apply the product rule for differentiation: (f\cdot g)'=f'\cdot g+f\cdot g', where f=2 and g=\cos\left(x\right). The derivative of the constant function (2) is equal to zero.
