Question statement

Solve the following equations in radians, for $\theta$ in the range $0\leq \theta\leq2\pi$ .

Give your answers rounded to 2 decimal places in ascending order.

The square root of $a$ is written as sqrt( $a$ ). $\theta$ is written as theta.

Give any introductory information the student needs.

Gap-fill

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

$\sin\theta-\sqrt{\var{a}}\cos\theta=0$

$\tan\theta=$ Gap 0.

$\theta=$ Gap 1. or Gap 2.

Advice

Please refer to the advice section of 'Trigonometric Equations 1 - Simple (Degrees)' for help.

You will need to use basic trigonometric identities in this question.

Please see this link if you do not know what these are.

To convert from degrees to radians, multiply by $\frac{\pi}{180}$ .

Give a worked solution to the whole question.
