A
Level Maths Notes: FP2 – Integrating Expressions Involving
Reciprocals of Sums of Trigonometric Functions Using the
Substitution![]()
To be able to use this method we have to express
and
in
terms of![]()
(1)
(2)
(3)
(4)
To evaluate any integral such as
or
we
make the substitution
and
use (1), (2), (3) and (4) above to express everything in terms of t
then integrate.
Example: Find
![]()
Sub (1) and (4)
