WebNov 11, 2024 · To write. -5 sin (Φ) - 4 cos (Φ) in the form of A sin (x + Φ), we start with. A sin (x + Φ) = A sin (x) cos (Φ) + A cos (x) sin (Φ) Then. A cos (Φ) = -5. A sin (Φ) = -4. The ratio of the second to the first equation is. sin (Φ) / cos (Φ) = -4 / -5. or simply. Webt = [2π − π/5] / ω = 4.2518 s. (iv) At minimum amplitude, x = −4, so we have −4 = 4cos(ωt + π/5) . Dividing through by 4, we get −1 = cos(ωt + π/5) . Taking the inverse of both sides, the solution is ωt + π/5 = cos−1(−1) , and thus, t = [cos−1(−1) − π/5] / ω .
