This topic is part of the HSC Mathematics Extension 1 syllabus under the topic Trigonometric Functions. In this post, we will be solving auxiliary angle questions using further trigonometric techniques. Auxilary angles take the following forms
R sin( \theta \pm \phi) = R (sin(\theta)cos(\phi) \pm sin(\phi)cos(\theta))
Solving Equations Using Auxiliary Angles
The following videos provide examples of solving equations using auxilary angles.
