Solve the following for tan²θ:
1 + tan²θ = sec²θ 

• tan²θ = sec²θ + 1
• tan²θ = sec²θ - 1
• tanθ = secθ - 1
• tan²θ = opp/adj

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

• tan²x
• sinx
• cot²x
• cosx

Simplify:  tanxcotx-cos²x

• tanx
• cotx
• sin²x
• cos²x

Is this a pythagorean identity?
tan²x + 1 = secx

• Yes
• No

Simplify this to a basic trigonometry function:
tan(x)csc(x) 

• tanx
• secx
• cotx
• cscx
