A.Quadrant II----
B.Quadrant IV
C.Quadrant I

A. x=2pi---
B.x=pi
C.x=1
D. x= 2pi/3

23. Find a positive angle less than one revolution around the unit circle that is co-terminal with the given angle: -40°

A. 40----
B.120
C.220
D.320


18. For the given function, state the amplitude and the maximum output for the function:

ƒ(t) = −3cos(t).


A.The amplitude is 3 and the maximum value is y = 6.
B.The amplitude is 3 and the maximum value is y = 3.---
C.The amplitude is 6 and the maximum value is y = 3.
D.The amplitude is 6 and the maximum value is y = 6.

Answer 2

Buhaha! Silly kitty! You get off of that hamburger! c:

Hmm secant normally has a mid line of y=0.
So +1 should do what to that? Not bring it up to y=2.

Answer 3

Hmm question 10 doesn't make sense.
csc(t) = 1/sin(t)

Sine and cosecant will always share the same sign.
So you can't have sin(t) < 0 and csc(t) > 0 at the same time.
Hmm maybe I"m forgetting something -_-

Answer 4

17 looks correct! c:

Answer 5

For #23, you need to spin your angle a full rotation.
-40 + 360

Answer 6

18 looks correct \c:/
