So this trig review is going to be about trig identities, how to solve trig equations & oblique triangle problems, and last but not least, polar graphs.
Trig Identities: You have to know these identities (except half-angle and sum/difference). Also the bottom two are necessary for solving trig integrals, so memorize those!
Trig Equations: Here are various example problems showing how to solve trig equations.
Oblique Triangle Equations: You only have to know the equilateral equation for area of cross sections in Calc BC. The rest is just extra info. that is nonetheless helpful to know. (:
Polar Graphs: Memorize these trig graphs for finding polar area! (All graphs come from Wolfram Alpha)
And that’s basically all the trig you need to know for Calc BC. Good luck! If you haven’t seen my part 1 post, you can find it here.
Here is some useful information that I’ve created about the basics of trigonometry as well as the graphs. Part 2 is out. You can find it here.
All graphs come from Wolfram Alpha (very cool resource).
Degrees & Radians; Six Trig Functions
Coterminal Angles, Arc Length, and Signs
The All Important Unit Circle (sorry, it’s a bit hard to see)
Those Pesky Trig Graphs
I have to know more graphs???
I hope this has helped you get closer to being a master at trig. More to come regarding trig identities and equations! (:
