$\sec\left(x\right)-\cos\left(x\right)$
Learn how to solve special products problems step by step online. Simplify the trigonometric expression sec(x)+-1/sec(x). Applying the trigonometric identity: \displaystyle\frac{1}{\sec(\theta)}=\cos(\theta). Applying the secant identity: \displaystyle\sec\left(\theta\right)=\frac{1}{\cos\left(\theta\right)}. Combine all terms into a single fraction with \cos\left(x\right) as common denominator. Apply the trigonometric identity: 1-\cos\left(\theta \right)^2=\sin\left(\theta \right)^2.
