Step-by-step Solution
Learn how to solve simplify trigonometric expressions problems step by step online. Expand and simplify the trigonometric expression (sin(x)+cos(x))^2. Expand the expression \left(\sin\left(x\right)+\cos\left(x\right)\right)^2 using the square of a binomial. Take the square of the first term: \sin\left(x\right). Twice (2) the product of the two terms: \sin\left(x\right) and \cos\left(x\right). Take the square of the second term: \cos\left(x\right).
Final answer to the problem
$1+2\sin\left(x\right)\cos\left(x\right)$
