Trigonometry : Displacement, Energy of Motion, Output Current, Amplitude and Phase Angle

2. The displacement of a body is given by s = 4 sin (t + 30 degrees), and a force acting upon the body is given by F = 7 sin (t — 60°). If the energy of the motion, E, at time t is the product Fs, show that E =—14 cos (2t — 30°) 3. Alternating currents i1 and i2 flowing into a circuit node are given by i1= 0.02 sin ωt a ...continues

Solve the Trigonometric Equations : (sin x)^2 = 1/36 and (cos x)^2 = 1/25

Solve for x. In each equation below, x has four roots. (a) (sin x)^2 = 1/36 (b) (cos x)^2 = 1/25 Note: Do not use caculator. The results should not contain floating points.

Use Identities to Simplify (Trig)

[sin(x)^4 - sin(x)^2]/[sec(x)]= I tried simplifying, but I get cos(x)^5 - cos(x)^3 and this isn't right.
