How would you find the period of y=-4sin(pi/3)x ?

-sorry, i dont know how to put the pi sybol in so I wrotwe it

-thanks for any help, J.T.

Given the general periodic function:

Hi !

Welcome in the forum ! There's the latex in here, just do or

See here : http://www.mathhelpforum.com/math-help/latex-help/ for more codes.

For your problem. The period T is defined such that f(x+T)=f(x).

So here

You know that the sine function is periodic. So it would be nice to find T such that we get this

Develop f(x+T) :

So find T such that and you're done (Wink) - August 26th 2008, 04:22 PMjem7vwhjt
