F t 12 cos t + 6 sin 2t 0 π/2

Websin 2t = 2 sin t cos t. cos 2t = cos 2 t – sin 2 t = 2 cos 2 t – 1 = 1 – 2 sin 2 t Less important identities You should know that there are these identities, but they are not as important as those mentioned above. They can all be derived from those above, but sometimes it takes a bit of work to do so. WebUsing the double angle formula, cos(2t) = 1−2sin2(t), we then find −2sin2(t)−sin(t)+1 = 0, Factoring this, we find −(2sin(t)−1)(sin(t)+1) = 0. Thus sin(t) = 1 2 or sin(t) = −1. In the first case, since t ∈ [0,π/2], we must have that t = π/6. In the second case, since sin(t) is nonnegative in the interval [0,π/2], there is no ...
