Example questions

Example 1 · 1 mark · multiple choice

What is the exact value of $sin 7 5^{\circ}$ ?

A $\frac{6 + 2}{4}$
B $\frac{6 - 2}{4}$
C $\frac{3 + 2}{2}$
D $\frac{1}{2}$

Example 2 · 2 marks · numerical answer

Use $cos (A - B) = cos A cos B + sin A sin B$ to find the exact value of $cos 1 5^{\circ}$ , then give it correct to four decimal places.

Example 3 · 2 marks · algebraic answer

Simplify $\frac{sin 2 x}{1 + cos 2 x}$ .

Answers and worked solutions appear when you practise these questions.
