A transverse wave on a rope is given by [tex]y(x, t)= (0.750\; {\rm cm})\, \cos ( \, \pi [(0.400\;{\rm cm}^{ - 1})x+(250\; {\rm s}^{ - 1})t])[/tex] Find the period. This should be simple, but I keep getting the wrong answer in Mastering Physics. I can't find any explanation in my book, and it's really irritating me.
Rewrite the equation in a standard form. y(x,t) = Acos[2*pi(x/lambda + t/T)] Compare this with the given equation and find the period.
