Key Points

The Product Rule is for differentiating a product of functions

A product of functions is simply two functions multiplied together

Sometimes you can use indices rules and then the power rule, rather than the product rule

The product rule can be written several ways – choose the one you can remember

Essentially the rule says ‘the 1st x derivative of the 2nd + 2nd x derivative of the first’

Learn the rule and practice applying it in different scenarios
