$\operatorname{cosec} A$
Express $\sin 67^{\circ}+\cos 75^{\circ}$ in terms of trigonometric ratios of angles between $0^{\circ}$ and $45^{\circ}$
Prove the following identities, where the angles involved are acute angles for which the expressions are defined.
$\frac{1+\sec A}{\sec A}=\frac{\sin ^{2} A}{1-\cos A}$
Write all the other trigonometric ratios of $\angle A$ in terms of $\sec$ $A$.
Evaluate $\frac{\tan 65^{\circ}}{\cot 25^{\circ}}$
State whether the following are true or false. Justify your answer.
The value of $\sin \theta$ increases as $\theta$ increases.
