#### Specialist Mathematics

Back to other subjects

# Integration Using Double-Angle Formulae

Integration Using Double-Angle Formulae is a part of the VCE Specialist Maths topic Calculus and subtopic Anti-Differentiation.

Here are the formulae:

##### Sine
sin(2x) = 2 sin(x) cos(x)
##### Cosine
cos(2x) = cos^2(x) -sin^2(x)  cos(2x) = 1 -2sin^2(x)  cos(2x) = 2cos^2(x) -1
##### Tangent
tan(2x) = \frac{2tan(x)}{1-tan^2(x)}

### Let’s Learn Double Angle Identities

This video will introduce you to double angle identities to help you learn to anti-differentiate them.
