Unformatted text preview: in QI and its reection 3 = 3 around the xaxis in QIV. Adding multiples of 2 to these gives us: 3 = 3 + 2 k for k = 0, 1, 2, . .. So dividing everything by 3 we get the general solution for : = 9 + 2 3 k for k = 0, 1, 2, . .. Example 6.7 Solve the equation sin 2 = sin . Solution: Here we use the doubleangle formula for sine: sin 2 = sin 2 sin cos = sin sin (2 cos 1) = sin = or cos = 1 2 = 0 , or = 3 = k and 3 + 2 k for k = 0, 1, 2, . .....
