Sketch, for 0≤x≤2π0 \leq x \leq 2\pi0≤x≤2π, the graph of y=sin(x+π6)\displaystyle y = \sin\left(x + \frac{\pi}{6}\right)y=sin(x+6π).
Write down the exact coordinates of the points where the graph meets the coordinate axes.
Solve, for 0≤x≤2π0 \leq x \leq 2\pi0≤x≤2π, the equation
sin(x+π6)=0.65, \sin\left(x + \frac{\pi}{6}\right) = 0.65, sin(x+6π)=0.65,giving your answers in radians to 2 decimal places.
