3 12 Smaller Triangle Larger Triangle sin = sin = cos = cos = tan 0= tan (= CSC = CSC = sec = sec = cot 8 = cot = Explain why the function values are the same. The triangles are similar so corresponding sides are proportional. The triangles are congruent so the trigonometric function values must be the same.
Find sin 0. 12 tan 0 = -, cos e>0 sin = (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression.)
6) Use the fundamental identities to find the values of sin(a), tan(a), and sec(a) if cos (a) 3 and tan (a)>0 5 (8 pts)
NOTE: Very useful trigonometric identities are these: sin(A B)-sin A cos B sin B cosA, cos(A +B)-COSA cos B-sin A sin B 32. (Bonus problem) A periodic function g(x)is defined on one period like this: g(x).0' on 1<x<0, and it equals x on 0<<1 (a) Give a labeled sketch of the graph of g(x), let's say from-1.5 to 3.5 (b) Give labeled sketches of, the graphs of g (x) and g(x) (i.e, the even and odd parts ofg).
