For $\displaystyle y=A\sin(Bx)$ or $\displaystyle y=A\cos(Bx)$, the period $\displaystyle T$ is:

$\displaystyle T=\frac{2\pi}{B}$ - Nov 13th 2012, 07:45 PMwhittwhittRe: Trig Help (finding period/inverses)
Ok, so the period for the first equation is 2pi/(1/3)?

And the second is 2pi/(xpi/24)? - Nov 13th 2012, 08:11 PMMarkFLRe: Trig Help (finding period/inverses)
For the first, you may simplify by using 1/(1/3) = 3, and for the second, you do not include x, and you may divide out pi, and bring the 24 up to the numerator.
