# Differentiating Simple Terms and Functions for AS & A-Level Maths

This is a handy guide to the building blocks of differentiation for A-level maths: it gives you all of the things you’re expected to know to differentiate (powers of *x*, exponentials, logarithms and trigonometric functions) and what you get when you do the calculus!

In the following table, *a* represents any constant.

Note that ln(*ax*) differentiates to *a* / *ax*, and after you cancel the *a*s you’re left with 1/*x*.
