When simplifying trig expressions, which of the following strategies could be helpful (check all that apply):

• Convert everything to sine and cosine

• Draw a picture

• Get a common denominator

• Factor

• Give up

Simplify. Hint: Factor out cos x.

• sin x

• cos x

• tan x

• 1

Please select the correct solution csc ² x - cot ² x=  

• sec ² x - 1

• 1

• sec ² x

• csc ² x - 1

Solve the following for cos²θ:
sin²θ + cos²θ = 1

• cos²θ = 1 - sin²θ

• cosθ = 1 + sin²θ

• cosθ = 1 - sinθ

• cos²θ = Adj/hyp

Please select the correct solution . hint: quotient identity

• csc x

• sec x

• cot x

• tan x

• sin²θ

• cosθ

• tanθ

• 1- sin²θ
