Trigonometric Equations (Edexcel A-Level Mathematics): Quizzes

Quadratic

$\sin^2 \theta + \cos^2 \theta = 1$

$\theta = \theta_0 + 180^\circ n$

$2\sin \theta \cos \theta$

$0^\circ$ to $360^\circ$

$30^\circ, 90^\circ, 150^\circ$

An angle more complicated than just $\theta$

$0 \leq 3\theta \leq 540$

$\theta_0$ and $180^\circ - \theta_0$

To ensure they satisfy the original eqn
