Ask the student a question, and give any hints about how they should answer this part.

Solve $tan(x)=\var{t}$ between $-\frac{\pi}{2}\leq x \leq \frac{3\pi}{2}$

Write your answers below in ascending order and to 3 significant figures.

$x=$ t1 $^c$ or t2 $^c$

Advice

WORKED SOLUTIONS

$\begin{align} tan(x)&=\var{t} \\\\ x_1&=tan^{-1}\var{t}=\var{t_1_3sf}^c \\\\ x_2&=\var{t_1_5sf}+\pi=\var{t_2_3sf}^c \end{align}$

Give a worked solution to the whole question.
