Write an equation of a cosine function with Amplitude=4, Period=pi/2, and Phase Shift=-pi?

Analysis
Find the amplitude, period, and phase shift of the functions: f(x)=4sec(x+3pi/2) f(x)=tan((1/3t)-pi) f(x)=-5sin(4t+3pi)

Analysis
Write an equation of a cosine function with Amplitude=4, Period=pi/2, and Phase Shift=-pi? Also write an equation of a cosine function with Amplitude=1/2, Period=6pi, and Phase Shift=pi/3?

Trig
If sin(t)=4/5 & 0<t<pi/2, find the following: a)sin t(-t) b) sin(t-2pi) c)cos t d)cos(pi-t)
