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.
