ABSTRACT
Functions that require integrating are not always in the ‘standard form’ shown in Chapter 115. However, it is often possible to change a function into a form that can be integrated by using either:
an algebraic substitution – see Chapter 117,
trigonometric and hyperbolic substitutions – see Chapter 118,
partial fractions – see Chapter 119

integration by parts – see Chapter 121, or
reduction formulae – see Chapter 122.
