Differentiation is a method to calculate the rate of change (or the slope at a point on the graph); we will not differentiate using the definition which requires some tricky work with limits; but instead we will use derivative rules that are fairly easy to memorize. We’ll start with the basics:

Constant: (c)’=0

Power rule: (xⁿ)’=nx^(n-1)

Multiplication by constant: (cf(x))’=c(f(x))’

Sum/difference rule: (f±g)’=f’± g’

We are good to go.

Let’s start with an example,
