Hey all, I want to prove that a function is periodic using the formula:(adsbygoogle = window.adsbygoogle || []).push({});

x(t) = x(t+T)

where T is the supposed period.

An example equation would be:

x(t) = 7sin(3t)

I would set up the equation like so:

7sin(3t) = 7sin(3*(t+T))

assuming that they equal each other:

3*t = 3*(t+T)

solving for T gives:

T = 0

but T = 0 = 2∏

am I right in assuming that it is periodic with a period of 2∏ or since T = 0 is it aperiodic?
