A
1/cos x
2
Q
What does Cosec x equal?
A
1/sin x
3
Q
What does cot x equal?
A
1/tan x
4
Q
How would you write 3Secθ ?
A
3/Cos θ
5
Q
How would you write 2/3Cosecθ ?
A
2/3Sinθ
6
Q
What steps would you use to solve sec θ = 3 ?
A
Rewrite as 1/Cos θ = 3
Rearrange so that Cos θ = 1/3
Do the inverse
Do 2π - Ans
7
Q
How would you solve Cot(θ -50°)=4
with interval 0°<θ<360°
A
Rewrite as 1/tan(θ -50°)=4
tan(θ -50°)=1/4
find inverse of tan(1/4)
π + Ans
+ 50 to answers

Q
What are the steps for drawing a reciprocal trig graph?
eg y = cosec x
A
y=cosec x= 1/sinx
1) draw sin graph
2)draw asymptotes where you have the issue of not being able to divide by zero
3)Draw curves
