I had actually posted this question earlier below one of my other questions but im pretty sure it was hidden and no one saw it because it was nestled under a few responses... so here:(adsbygoogle = window.adsbygoogle || []).push({});

A periodic wave has the equation .15m*sin(10t+(pi)x)

Now i am getting a little bit mixed up about how to determine the direction of the wave... Im going to say this wave is moving in a positive direction because (pi)x is positive... meaning it is going forward... is that correct? So when i rewrite the equation it would be .15m*sin(10t+(pi)(x-vt)) to account for the positive change? Thanks for all of the help guys.
