Some needed trig identities:. Trig Derivatives. Graph . y. 1. = sin x. . and . y. 2. = . nderiv. (sin x). What do you notice?. Proof Algebraically. (use trig identity for . sin(x + h). ). Proof Algebraically. We have already discussed a few example of trig identities. All identities are meant to serve as examples of equality. Convert one expression into another. Can be used to verify relationships or simplify expressions in terms of a single trig function or similar. Use the triangle given to find the following trig ratios. sin( θ ) cos ( θ ) tan( θ ) Solve for x in the proportions below. 5.   Warm Up 1/20 Get out a colored pen and last night’s homework transformations of these graphs. LO: SWBAT state the transformations of the sine and cosine. Graphs in words.. CO: SWBAT generate the graphs of the sine and cosine functions and explore various . transformations of these graphs. LO: SWBAT state the transformations of the sine and cosine.
