Derivative Rules for Combinations of Functions
mathstat.slu.edu › ~may › ExcelCalculusWe want rules for multiplying a known function by a constant, for adding or subtracting two known functions, and for multiplying or dividing two known functions. Subsection 4.2.1 Derivatives of scalar products. We start by differentiating a constant times a function. Claim 4.2.1. Scalar multiple rule. The derivative of \(c*f(x)\) is \(c*f'(x ...

The derivative of the product of two functions is the derivative of the first one multiplied by the second one plus the first one multiplied by the derivative of the second one. Mathematically, f ( x) = g ( x) h ( x) ⇒ f ′ ( x) = g ′ ( x) h ( x) + g ( x) h ′ ( x)
