Simple harmonic motion (Again) :(
This is not a question about a problem it is more about the position of a simple harmonic oscillator as a function of time:)
I went through it in a lecture yesterday and found using the energy in simple harmonic motion to bex(t)= A cos(ωt +φ)
Which is fine the proof seems ok but when I look through my university textbook for some supplementary work on the subject I found that the book had something slightly different.
x(t)= A sin(ωt +φ)
Why is this that case?I should also say I googled and looked in other books and found a mixture of the two equations although I did notice that a lot of the time when it was written sine, the argument didn't contain a phase constant...
x(t)= A sin(ωt)
Which makes me think it has something to do with the phase constant but I'm not sure because my university textbook includes the phase constant and also the sine of the argument it's contained in:)Thanks for your help in advanced
