Wave function of infinite square well but with time dependence included

[Raziel2701]

Homework Statement

Find the wavefunction for an infinite well, walls are at x=0 and x=L(include the time dependence)

The Attempt at a Solution

I don't understand what it's meant by include the time dependence. Can I just find the time-independent wavefunction and then multiply it by $$e^{-iwt}$$ ? Or do I have to start from the Schrödinger equation?

Don't worry I got it after all.
