$\frac{1}{\csc\left(x\right)-\cot\left(x\right)}+\frac{1}{\csc\left(x\right)+\cot\left(x\right)}$
Learn how to solve trigonometric identities problems step by step online. Prove the trigonometric identity 2csc(x)=1/(csc(x)-cot(x))+1/(csc(x)+cot(x)). Starting from the right-hand side (RHS) 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}. Any expression multiplied by 1 is equal to itself. Any expression multiplied by 1 is equal to itself.
