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.
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
