4
- Find the possible values of \(\tan \theta\), giving your answers in exact form.
4 - Hence, or otherwise, solve the equation
$$5 \cos ^ { 2 } \theta - 4 \sin ^ { 2 } \theta = 0$$
giving all solutions of \(\theta\) to the nearest \(0.1 ^ { \circ }\) in the interval \(0 ^ { \circ } \leq \theta \leq 360 ^ { \circ }\)
