$\frac{\cos\left(x\right)-\sin\left(x\right)}{\sin\left(x\right)+\cos\left(x\right)}$
Learn how to solve factor by difference of squares problems step by step online. Prove the trigonometric identity sec(2x)-tan(2x)=(cos(x)-sin(x))/(sin(x)+cos(x)). Starting from the right-hand side (RHS) of the identity. Multiply and divide the fraction \frac{\cos\left(x\right)-\sin\left(x\right)}{\sin\left(x\right)+\cos\left(x\right)} by the conjugate of it's denominator \sin\left(x\right)+\cos\left(x\right). Applying the trigonometric identity: \sin\left(\theta \right)^2-\cos\left(\theta \right)^2 = -\cos\left(2\theta \right). Multiply the single term \sin\left(x\right)-\cos\left(x\right) by each term of the polynomial \left(\cos\left(x\right)-\sin\left(x\right)\right).
