TrigonometryYear 12 (age 16-17)

1. Sketch for 0 to 360°, sin x, cos x, tan x

2. Solve for x (and draw sketches)  (a) sin x = 0.5  (b) cos x = 0.6   (c) tan x = -0.1

3. Solve sin x =  2cos x

4. Solve 3sin2θ+5cosθ=1

5. Write down the formulae for the area and arc length of a sector where the angle is in radians.
