Simplify Trig

• -1

• sin θ

• csc θ

• 1

Simplify by distributing.. hint: What is anything times its reciprocal?

• secθ

• cos²θ

• sin²θ

• sin²θ/cos²θ

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

• tan²x

• sinx

• cot²x

• cosx

• tanx

• cotx

• sin²x

• cos²x

Simplify this to a basic trigonometry function:

tan(x)csc(x) . Hint: I used quotient and reciprocal identities on this one.

• tanx

• secx

• cotx

• cscx

cos x = 0

• 1/cos x

• 1

• cot x

• -1

Simplify
(sec x)(cot x)(sin x)

• sin x

• - sin x

• 1

• -1

Simplify

• -1

• sin θ

• csc θ

• 1

cscx/secx is equivalent to

• tanx

• cosx

• sinx

• cotx

Simplify:  tanxcotx-cos²x

• tanx

• cotx

• sin²x

• cos²x
