$\cot\left(a\right)\tan\left(a\right)+\sin\left(a\right)\sec\left(a\right)$
Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity cot(a)tan(a)+sin(a)sec(a)=1+tan(a). Starting from the left-hand side (LHS) of the identity. Applying the trigonometric identity: \cot\left(\theta \right) = \frac{1}{\tan\left(\theta \right)}. Multiplying the fraction by \tan\left(a\right). Applying the secant identity: \displaystyle\sec\left(\theta\right)=\frac{1}{\cos\left(\theta\right)}.
