Please select the correct solution

• csc² x
• cot² x
• sin² x
• sec² x

Please select the correct solution

• csc x
• sec x
• cot x
• tan x

Which of the following would be a step to prove the following identity?

• (1/ sin x) - (1 / cos x)

• (cos x - sin x) / ( sin x)

• (cos x - sin x) / (cos x)

• (1/ sin x cos x)

Verify the following

• (1 + cosx) / (cos x)

• (1) / (sin x)

• (1 + sinx) / (sin x)

• (sinx) / (sin x)

Verify the following:

• cos²x

• sin²x

• cot²x

• tan²x

Solve the following for cos²θ:
sin²θ + cos²θ = 1

• cos²θ = 1 - sin²θ
• cosθ = 1 + sin²θ
• cosθ = 1 - sinθ
• cos²θ = Adj/hyp
