Question 1 Because the period is 2π, and the amplitude is 1obtain f(x) = sin(x) Because the horizontal shift is π, obtain f(x) = sin(x - π) Because the vertical shift is -4, obtain f(x) = sin(x - π) - 4
Answer: 1. f(x) = sin(x - π) - 4
Question 2 The radius is 36/2 = 18 in. 1 revolution (360°) is the circumference, which is 2π(18) = 36π in When the revolution is 62°, the distance traveled is (62/360)*(36π) = (31/5)π in
