Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity (sec(x)+1)(sec(x)-1)=tan(x)^2. section:I. Express the LHS in terms of sine and cosine and simplify. Start from the LHS (left-hand side). The sum of two terms multiplied by their difference is equal to the square of the first term minus the square of the second term. In other words: (a+b)(a-b)=a^2-b^2.. section:II. Express the RHS in terms of sine and cosine and simplify.
