Pre-Calc Final S2 Review 1

sin²x + cos²x =

• 1

• 1/sinx

• sec²x

• csc²x

1 - sin²x =

• cos²x

• cos²x+1

• csc²x

• tan²x

sec²x =

• sinx + cosx

• 1 + csc²x

• 1 + tan²x

• 1 - sin²x

Rewrite tan(x) in terms of sin(x) and cos(x).

• tan(x) = cos(x)/sin(x)
• tan(x) = 1/cot(x)
• tan(x) = sin(x)/cos(x)
• tan(x) = opp/adj

Simplify
