I haven't taken a geometry course in a few years and I'm trying to review what I learned in my Alg II classes for Pre Calc.

Trigonometry is normally incorporated into a Precalculus course.

My precalculus course included trigonometry involving cos + i sin and I think polar graphing. You can read https://en.wikipedia.org/wiki/Trigonometric_functions and see if you can understand it. Last edited by EvanJ; October 20th, 2015 at 03:00 PM.

If a high school offers precalculus, then they normally do not offer a separate trig course, but there are exceptions. At the college level, check the course offerings catalog from where you want to go and see if prerequisites are required for taking precalculus. You may have to take a placement exam.

Here is what Hofstra University says about a prerequisite for Precalculus: "A grade of Pass in MATH 006A or Math Placement scores as interpreted by advisement. May not be taken after MATH 071 or after receiving a passing score on the Calculus Readiness Exam without prior permission of the department chairperson." MATH 006A is titled "The Real Numbers and College Algebra." MATH 071 is titled "Analytic Geometry and Calculus I." http://www.opentextbookstore.com/precalc/ has a Precalculus textbook online for free. Considering that half the chapters involve trigonometry, I recommend knowing some Trigonometry before taking Precalculus. Last edited by EvanJ; October 23rd, 2015 at 10:35 AM.

But, while I aced those classes, there were several times throughout my college career when I found myself ignorant of some topic and my classmates were like, "Didn't you take precalculus?" So, on reflection, I think I would have been better off delaying calculus one semester and making sure I had the background required. The same is probably true of you regarding trigonometry.
