Sample Question 1
Which reciprocal identity is correct?

Tan(θ) = 1/cos(θ)

Cos(θ) = 1/sec(θ)

Sec(θ) = 1/sin(θ)

Csc(θ) = 1/tan(θ)

Sample Question 2
Simplify completely: sin(θ)·csc(θ) + cos(θ)·sec(θ)

0

1

2

Sin(θ) + cos(θ)

Sample Question 3
Rewrite using only sine and cosine: cot(θ)

Sin(θ)/cos(θ)

Cos(θ)/sin(θ)

1/(sin(θ)cos(θ))

Sin²(θ)
