sketch the graph of the following function

Sketch the graph of the function (include two full periods). y=csc (Pi - x) y=1/4 csc (x + Pi/4) y=2 sec (2x - Pi)

verify that each trigonometric equation is an identity

cos0/ sin0 cot0 = 1

Use the identities of this section to find the exact value

sin pi/12

solve y=a cos bt with t measured in seconds

s(t) = -4 cos 10t inches after t seconds. A)What is the maximum height that the weight rises above the equilibrium position? is this righ? 4inches B)What are the frequency and period of the system? is this right? 4pi/4 c)When does the weight first reach its maximum height? is this right? after 4 cycles d)calculate and interpret s(1.466).
