This recording demonstrates how to integrate rational functions where the numerator is a constant and the denominator is a linear function. Integration by substitution is used.

#### MathsCasts: Transposition with Required Variable in the Denominator

(Swinburne Commons, 2013)

In this recording we look at how to rearrange a formula where the letter that we want to make the subject is in the denominator. That is, we look how to make f the subject when presented with an expression of the form a/b ...

#### MathsCasts: Integrating Rational Functions Part 2

(Swinburne Commons, 2013)

This recording demonstrates how to integrate rational functions where the numerator is a constant and the denominator is an irreducible quadratic function. We complete the square on the denominator, then we integrate by ...
