What is this a graph of
arccos function
tan function
sec function
arcsin function
2
What is this graph of
Cos Function
Csc Function
Sin Function
Sec Function
3
What is the area of this triangle
17.89
11.75
8.55
23.49
4
what is this a graph of
Sec Function
Cot Function
Csc Function
Tan function
5
convert r=4sec to rectangular coordinates
y=4x
y=1/4x
x=4
y=4
6
what is the correlation between Sin and Csc functions
theyre the same function
There is no correlation
local max of one is equal to the local min of the other
Csc(x) is just Sin(x + π)
7

What is the frequency of this Sin graph: 4 sin (2x/3)
π/3
1/3π
3/π
1/π
12
which of these functions is true
cos x = sin (x + π/2)
sin x = cos (x - π/2)
sin (x + π/2) = cos (x - π/2)
sin x = cos x
13
Which of these is not a trigonometry identity
tan2 + sec2 = 1
sin(u+v) = sinucosv + cosusinv
cot2 + 1 = csc2
tan = sin/cos
14

-√3
√3
√3/3
-√3/3
