<p>I'm going into my junior year and I will be taking Precalculus (Functions/Trig) and I was wondering if I should take AP physics or regular? My only concern is that I won't be able to handle the math. I haven't learned trig yet but i will this year. Will I like absolutely bomb this class just because i haven't done trig yet? I took Algebra 2 last year and got an A. And oh i'm referring to AP Physics B. The algebra based one.</p>
<p>The only trig stuff you new in AP physics B is the trig identities. I believe you (should have) learned it in geometry when you learned 30-60-90 triangles. We use sine, cosine, and tangent a lot. It’s not like it’s trig base. It’s, so far, manipulating equations to get what you’re looking for.</p>
