Express \(5 \cos 3 t+2 \sin 3 t\) in the form \(A \cos (\omega t+\alpha), \alpha \geq 0\)
From Table \(5.1\) we have $$ \cos (A-B)=\cos A \cos B+\sin A \sin B $$ Verify this identity when \(A=80^{\circ}\) and \(B=30^{\circ}\),
In \(\triangle \mathrm{CDE}, D\) is a right angle. The lengths of \(\mathrm{CD}, \mathrm{DE}\) and \(\mathrm{CE}\) are \(\alpha, \beta\) and \(\gamma\) respectively. State (a) \(\sin C\) (b) \(\cos C\) (c) \(\tan C\) (d) \(\sin E\) (e) \(\tan E(\) f) \(\cos E\)
Solve $$ \sin 2 \theta=-0.4010 \quad 0 \leq \theta \leq 2 \pi $$
Simplify $$ \tan A+\frac{1}{\tan A} $$
