Hi,
I just learned my first equation today in SHM:
Firstly, is it ok if I change the "x =" part for a "y="? I get a bit confused since, from what I understand, we want to find the vertical distance from the x-axis and that would be the y output of a function. (x makes me think of the input)
I understand the first x, representing the displacement - stretching the graph parallel to the y axis.
Now, the (ω * t) part is what confuses me. Those values will determine where in the curve we want to find the displacement, correct? If so, how do the ω and time represent which part in the curve we are looking for, like the angles we input in our calculators do?
I hope I conveyed my doubts in a clear enough way,
Thanks,
Peter G.
