geerky42 · Answer

All of them do. Not all have the same period, though.

anonymous · Answer

the period 2 pi. sorry if you could please explain how to find the period I would greatly appreciate it

jim_thompson5910 · Answer

for sine and cosine, the general form is 

y = A*sin(Bx-C) + D

y = A*cos(Bx-C) + D

-------------------------------------------------------

in both cases, the period is T = 2pi/B

jim_thompson5910 · Answer

so for instance in y = 2*sin(3x-7)

B = 3

Period

T = 2pi/B

T = 2pi/3
