Simplifying and Solving Trig Equations

Simplify; remember the first step is to write all of the terms in terms of sines and/or cosines.

• cotx

• tanx

• cosx

• sinx

Simplify. Remember, with all terms multiplied (or divided) you can simply cancel factors from the numerator and denominator.)

• cosx

• sinx

• secx

• cscx

• None of these are correct

• π/2, 3π/2

• 0, π,2π

• 2π/3, 4π/3

• π/3, 5π/3
