WebNov 12, 2016 · Substitute 1 − sin2(θ) for cos2(θ): 2(1 −sin2(θ)) +3sin(θ) = 0. Use the distributive property: 2 − 2sin2(θ)) + 3sin(θ) = 0. Multiply both side by -1: 2sin2(θ)) −3sin(θ) −2 = 0. This is a quadratic where the variable is sin(θ). It looks like it will factor: # (sin (theta) - 2) (2sin (theta) + 1) = 0.

Webo 60 oo o Figure 8. A graph of tanu. We know from the Table on page 2 that one angle which has a tangent equal to √ 3 is u = 60 . We can use the symmetry of the graph to deduce others. These are u = −300 ,−120 ,60 ,240 But u = 2x and so 2x = −300 ,−120 ,60 ,240 and so the required solutions are x = −150 ,−60 ,30 ,120 Exercise1
