Identity Relating Secant and Tangent

Identity Relating Cosecant and Cotangent

Assertion (A) : For an angle θ, sec θ = 1 ⇒ tan θ = 0. Reason (R) : sec² θ + tan² θ = 1.

If sec θ - tan θ = 2, then sec θ + tan θ is equal to :

Which one of the following is not equal to Unity?

Prove that : (sinx − cosx + 1). (secx − tanx) = (sinx + cosx − 1)

If secθ - tanθ = 2, then secθ + tanθ is equal to :
