Hi everyone! Our unit on Trigonometric Identities has come to an end. I really enjoyed this unit. We learned the different identities of trigonometry, especially the wicked awesome cool Sine Dance! XD

We also learned that we don't have to memorize all those Trig ID's. Mr. K said that we just need to memorize a few, such as sin^2(θ) + cos^2(θ) = 1. We can derive the other identities from them.

Mr. K said, "The only way to get good as this, is to do more of this..." For me, its a very good thing if you keep on practicing these problems. For some reason, the ID's get stuck in your head if you keep practicing and practicing.

I hope everyone will do well on the next test. NO PROCRASTINATING! XD
