$\sec\left(x\right)$
Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity sec(x)=1/cos(x). Starting from the left-hand side (LHS) of the identity. Applying the secant identity: \displaystyle\sec\left(\theta\right)=\frac{1}{\cos\left(\theta\right)}. Since we have reached the expression of our goal, we have proven the identity.
