Sec θ – \(\frac {1}{sec \, \theta }\) is _____(a) Tan θ / Sec ⁡θ(b) Tan^2 θ / Sec ⁡θ(c) Tan θ / Sec^2 ⁡θ(d) Sec⁡ θ / Tan ⁡θThis question was posed to me during an online exam.My question comes from Trigonometric Identities topic in section Trigonometry of Mathematics – Class 10

Answer»

Correct option is (b) Tan^2 θ / SEC ⁡θ

The EXPLANATION is: Sec θ – \(\frac {1}{sec \, \theta } = \frac {1}{sec \, \theta }\)(Sec^2 θ – 1)

= \(\frac {1}{sec \, \theta }\)(Tan^2 θ)

= Tan^2 θ / Sec ⁡θ
