$\left(1+\sin\left(x\right)\right)\left(1-\sin\left(x\right)\right)$
Learn how to solve identità trigonometriche problems step by step online. (1+sin(x))(1-sin(x))=cos(x)^2. Starting from the left-hand side (LHS) of the identity. Apply the formula: \left(a+b\right)\left(a+c\right)=a^2-b^2, where a=1, b=\sin\left(x\right), c=-\sin\left(x\right), a+c=1-\sin\left(x\right) and a+b=1+\sin\left(x\right). Apply the trigonometric identity: 1-\sin\left(\theta \right)^2=\cos\left(\theta \right)^2. Since we have reached the expression of our goal, we have proven the identity.
