What's the name of the topic?

We haven't covered this yet.

I may look it up for you though, so let me know the topic name.

CLICK HERE

Look at page 2.

This is from AP Physics Notes, but I think that's what you are talking about.

Hope it helps.

ya its x sin wen at t=0 the particle is at its equilibrium position tht gives u a sine curve
n x cos wen at t=0 particle is at its max displacement thid gives u a cos curve
chk ur notes gurl
nythin else do lemme noe
i hope i made it clear =)
