$\cos\left(\infty\right)\left(\sec\left(\infty\right)+\tan\left(\infty\right)\right)$
Learn how to solve proving trigonometric identities problems step by step online. Prove the trigonometric identity cos(infinity)(sec(infinity)+tan(infinity))=1+sin(infinity). Starting from the left-hand side (LHS) of the identity. Multiply the single term \cos\left(\infty\right) by each term of the polynomial \left(\sec\left(\infty\right)+\tan\left(\infty\right)\right). Simplifying. Applying the tangent identity: \displaystyle\tan\left(\theta\right)=\frac{\sin\left(\theta\right)}{\cos\left(\theta\right)}.
