Note: This only works when \(x\) is measured in radians. We are now going to look at more complex trigonometric functions where we will use the general rule: \(\int {\cos (ax + b)dx = \frac{1}{a ...

Brackets are used to add words to improve understanding ... where it is best to paraphrase a source instead of integrating a whole quote into the paper. Quote integration is crucial when the exact ...

Similar rules apply to integration whereby we need to remove the brackets first as the expression has to be sums and/or differences of terms of the form \(a{x^n}\).
