$\frac{\sin\left(x\right)}{1+\sin\left(x\right)}+\frac{\sin\left(x\right)}{1-\sin\left(x\right)}$
Learn how to solve problems step by step online. Prove the trigonometric identity sin(x)/(1+sin(x))+sin(x)/(1-sin(x))=2tan(x)sec(x). Starting from the left-hand side (LHS) of the identity. Combine fractions with different denominator using the formula: \displaystyle\frac{a}{b}+\frac{c}{d}=\frac{a\cdot d + b\cdot c}{b\cdot d}. 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.. Expand the expression \sin\left(x\right)\left(1-\sin\left(x\right)\right)+\sin\left(x\right)\left(1+\sin\left(x\right)\right) completely and simplify.
