CHapter 5 key terms

Question 1

pythagorean identities

Answer 1

1. 1 + tan^2t = sec^2 t
2. cot^2t + 1 = csc^2 t
3. sin^2t + cos^2t = 1

Question 2

cofunction identities

Answer 2

The cofunction identities show the relationship between sine, cosine, tangent, cotangent, secant and cosecant. The value of a trigonometric function of an angle equals the value of the cofunction of the complement

Question 3

cos

Question 5

when finding max and decreasing, and increasing

Answer 5

you graph and determine increasing, and decreasing all going from left to right, and with negative you change all values exact trig values (90, 180, 270, 360)
