I’m currently self studying algebra II and trigonometry, and I’m almost done with algebra II part, which means it’s almost time for me to get going on trigonometry.
I’ve been using KA and I have a textbook, so here’s the minimum topics I’ll be covering (sorry for length):
From the textbook (I made a checklist thing and pasted here, that’s why it has all the lines):
_______ Trigonometric Functions in Triangles
_______ More on Trigonometric Functions
_______ Radians, Cofunctions, and Problem Solving
_______ Finding Function Values: Tables and Calculators
_______ Graphs of Trigonometric Functions
_______ Trigonometric Function Relationships
_______ More Trigonometric Graphs
_______ Algebraic Manipulations
_______ Sum and Difference Identities
_______ Double-Angle and Half-Angle Identities
_______ Proving Identities
_______ Inverses of the Trigonometric Functions
_______ Trigonometric Equations
_______ Rights Triangles and Problem Solving
_______ The Law of Sines
_______ The Law of Cosines
_______ Trigonometric Notation for Complex Numbers
Additional topics from KA:
Basic trigonometric ratios
Trigonometric ratios and similarity
Trig ration application problems
Reciprocal trig functions
Radians
Trig problems on the unit circle
Trig functions of special angles
Graphs of trig functions
Modeling with periodic functions
Tau vs pi
Symmetry and periodicity of trig functions
Pythagorean identity
Angle addition formulas
Angle addition formula proofs
Trig identities
Advanced trig examples
Although this is long enough to be obnoxious to post, lol, it really isn’t very long since there’s a lot of overlap and I’ll have ~5 months. I know that it varies by school, but can anybody suggest resources that will prepare me well for precalc? I looked at Life of Fred and it looks great, but it’s more extensive that what I want now. Or is the trig needed for precalc so minimal that I don’t need to go beyond this?
