I am trying to prepare to understand calculus ( precalculus) do I need to have the skills to solve trignometric identity and sinusoidal equations. On my dash board there are trignometric skills in pre-calculus. I am totally lost. I understand the basics of trig, but where can I learn trig identities. I have missed something here.

Yes, trig is a huge part of pre-calculus. Here is the section of Trigonometry that deals with equations and identities: https://www.khanacademy.org/math/trigonometry/trig-equations-and-identities

I have a similar problem. I've gotten to "Solve sinusoidal equations", but there are no lessons explaining how to do it, I've spent 3 days trying to figure it out, and I still get every question wrong.
