Question

State the amplitude, period, and phase shift of the function -3cos(3x+3 pi/2).

Answer 1

try the physics section! but from what i recall.... this is a standard sinusoidal wave function where the generic version looks like D(x)=Acos(wt+phase shift) or something close to it..... so the amplitude would be 3... and the phase shift would be 3pi/2.... but check and make sure that D(x) equation is exactly correct... bc its been awhile haha

Answer 2

physics?! woah, i'm in pre-cal. this is trig.

Answer 3

haha ok. well it looks very similar to a physics theorem, sorry about that...
