Homework 3/10 1. (a) y = cos x (b) y = cos(6 x ) (c) y = cos( x 6 ) 2. (a) y = tan x (b) y = tan πx (c) y = tan( x 2 + 5 x ) 3. (a) y = x 4 (b) y = (sin x ) 4 (c) y = cos 4 x 4. (a) y = x (b) y = tan x (c) y = cot x 5. (a) y = e x (b) y = e x 2 +3 x (c) y = e sec x 6. Section 3.5: 9-21 odd. Just fnd y . Don’t worry about rewriting the Function. Answers 1. a) - sin x ; b) - 6 sin 6 x ; c) - 6 x 5 sin x 6 . 2. a) sec 2 x ; b) π sec 2 πx ; c) (2 x + 5) sec 2 (2
