Uses of partial fractions

Partial Fractions are used to turn functions that cannot be integrated into simple fractions that can.

When the denominator is linear the integration will use logarithms.

When the denominator is a quadratic, you may still be able to use logarithms, but probably will need to use a trigonometric integration rule (usually studied in Further Maths, so check with your teacher if you need to know about this).

By rewriting a function as partial fractions, we are able to make approximations to the value of the function using the binomial expansion.
