You can put this solution on YOUR website! Which of these functions has period 7?
A. y= sin(7/pi)x
B. y= cot(7/pi)x
C. y= cos(pi/7)x
D. y= tan(pi/7)x
--------------------
sine & cosine of x --> period of 2pi
tan and cot of x --> period of pi
---
tan(pi*x) --> period of 1
tan (pi*x/7) --> period of 7
