Determine the amplitude and period of the function rt=0.5cos(t-π/2)+3 without graphing the function first. Sketch a graph of the function after determining its period and amplitude, then label the period and amplitude. All inputs are in radians.

Step 1
The standard form of a cosine function is \( y = A \cos(B(t - C)) + D \), where: - \( A \) is the amplitude, - \( B \) affects the period, - \( C \) is the phase shift, - \( D \) is the vertical shift. Show more…
