What is csc(x) equivalent to?

What is sec(x) equivalent to?

Please select the correct solution 
cos ² x + sin ² x=  

• 1
• csc ² x + sec ² x
• sin ² x
• 1 - sin ² x

Solve the following for cos²θ:
sin²θ + cos²θ = 1

• cos²θ = 1 - sin²θ
• cos²θ = 1 + sin²θ

• cos²θ = 1 - sinθ

• cos²θ = Adj/hyp

Solve the following for tan²θ:
1 + tan²θ = sec²θ 

• tan²θ = sec²θ + 1
• tan²θ = sec²θ - 1
• tan²θ = secθ - 1

• tan²θ = opp/adj
