Hey guys,
For high school math I've taken geometry and alg. 2 I'm on track to take pre calc and calc, do I need to take trigonometry in order to apply? Thank you

I am pretty sure that most pre-calculus is trig. At my DS's high school it was called Math Analysis as opposed to Pre-Calculus or Trigonometry.

Check with your guidance counselor, course catalog, or math teacher to know for sure. Best wishes.

Ask one of the pre-calc teachers if trigonometry is included in the curriculum. At my school it was, but I've heard that for others it was a separate course.

Trig is the single most important math subject you can take in high school if you're planning on going into higher math classes like calc. It's so fundamental I don't know what I'd do without it. You'll use it so much that it'll become second nature to you. Your school should give you guidance on this... If you're on track to take calc your senior year, I couldn't imagine you having not taken trig. So yes, you have to take it.

I took trig sophomore year and it was for a semester. Now it is meshed into Algebra 3 or pre-calc. Something like that. But yeah it is valuable, I would take it.

You'll learn trigonometry in Pre-calc. There's no way you can do polar functions without trig.

So with taking Pre-Calc next year and Calc my last year I should still be able to be a candidate?

Not sure how you haven't learned trig by now if you're looking at Calculus. You probably have learned it and just didn't notice. If you really haven't learned it (like you literally have no clue what sine, cosine, and tangent are), then it's not difficult to pick up with some help.

That said, I would definitely clear it with your math instructors. It's a trivial topic to learn (most schools mash a few weeks of trig together with an Algebra 2 or Geometry course), but it is important.

Thanks for the help

I've learned trig in geometry, a little in all 2 and probably will in pre-Calc, but will USNA still accept my Application without having an actual class called trig?
Thanks

Yes, we don't have a specific trig class in our high school either. It is rolled in with advance algebra. DS still made it all the way to AP calc.
