To verify the identity (sec⁡θ−1)(sec⁡θ+1)=tan⁡2θ(\sec\theta - 1)(\sec\theta + 1) = \tan^2\theta, which side is generally simpler to start simplifying? (a) Either side requires the same effort (b) Right-hand side tan⁡2θ\tan^2\theta (c) Left-hand side (sec⁡θ−1)(sec⁡θ+1)(\sec\theta - 1)(\sec\theta + 1) (d) The identity cannot be verified with fundamental identities
