Lately, I have been trying to get a deeper understanding of a few concepts, and I was trying to analylize a wave I found in my text book:(adsbygoogle = window.adsbygoogle || []).push({});

I know the sinusoidal equation is:

[itex]Vs = Vm*sin({\omega}t + {\phi})[/itex]

The equation for the given wave is:

[itex]Vs = Vm*sin(4t + 30^o)[/itex]

My question is how does the 4t change this graph? Also, What does the phase angle change*?

If the equation was just [itex]Vs = Vm*sin(4t)[/itex], how would the graph change?

Thank you!

PS - Please excuse the terrible mspaint graph!
