Analytical Trigonometry Resources

For a nice, slow, in depth approach to symmetry of trig functions, check this out. It gives visuals and some examples to work through in order to get more comfortable with what even and odd trig functions are.

This provides a good explanation of the domain restrictions on inverse trig functions and why we have them. It also gives a visual of what an inverse trig function looks like on a graph.

A compilation of trig identities. This will save you from leafing through everything whenever you need to remember a formula.

The addition formula for sine (and cosine, for that matter) can be pretty tricky to derive, so having a video handy is definitely a good idea. From here you can get to proofs of other identities too.

This goes more in-depth about when to use the Law of Sines and the Law of Cosines. It's always a good idea to know when to use things.

This walks through how to graph a trig function. It also gives a good explanation of what all of the variables in the y = Asin(Bx +C) +D form mean on the graph.

This works just like a graphing calculator, but online. It also gives more information that you would probably ever want to know about the function being graphed, in case you are curious.

If you're looking for more practice with knowing the trig values of some basic angles, this will help drill it into you.

If you thought you left flashcards behind when you left basic math (we're sure you long for the simpler days of 1 + 1 = 2), think again. There are flashcards for trig! It's good practice with finding trig values and inverses.

Here is a whole lineup of games/activities to help you memorize the trig identities. With some variety you can review in a few ways to really make sure you know them all.
