$\cot\left(x\right)-1=\cos\left(x\right)\csc\left(x\right)-\cos\left(x\right)\sin\left(x\right)$
Learn how to solve problems step by step online. Solve the trigonometric equation cot(x)-1=cos(x)(csc(x)-sin(x)). Multiplying polynomials \cos\left(x\right) and \csc\left(x\right)-\sin\left(x\right). Simplify \cos\left(x\right)\csc\left(x\right) into \cot(x) by applying trigonometric identities. Simplify -\cos\left(x\right)\sin\left(x\right) using the trigonometric identity: \sin(2x)=2\sin(x)\cos(x). Move everything to the left hand side of the equation.
