Which of these problems would need the conjugate:

• 
• 
• 
• 

What would be the first step here?

• Give up and cry

Simplify

• sin²θ

• cosθ

• tanθ

• 1- sin²θ

Simplify

• -1
• sin θ
• csc θ
• 1

Simplify:
(secx-1)(secx+1).  
Hint: you will need to FOIL first

• tan²x
• sinx
• cot²x
• cosx

cotθ=
