$\frac{\frac{\cos\left(x\right)-1}{\cos\left(x\right)}}{1+\frac{1}{\cos\left(x\right)}}$
Learn how to solve product rule of differentiation problems step by step online. Find the derivative using the product rule (1+-1/cos(x))/(1+1/cos(x)). Combine all terms into a single fraction with \cos\left(x\right) as common denominator. Combine all terms into a single fraction with \cos\left(x\right) as common denominator. We can simplify the quotient of fractions \frac{\frac{\cos\left(x\right)-1}{\cos\left(x\right)}}{\frac{\cos\left(x\right)+1}{\cos\left(x\right)}} by inverting the second fraction and multiply both fractions.
