Learn how to solve one-variable linear equations problems step by step online. Find the derivative of (1+-1/cos(x))/(1+1/cos(x)). Combine 1+\frac{1}{\cos\left(x\right)} in a single fraction. Combine 1+\frac{-1}{\cos\left(x\right)} in a single fraction. Simplify the fraction \frac{\frac{-1+\cos\left(x\right)}{\cos\left(x\right)}}{\frac{1+\cos\left(x\right)}{\cos\left(x\right)}}. Apply the quotient rule for differentiation, which states that if f(x) and g(x) are functions and h(x) is the function defined by {\displaystyle h(x) = \frac{f(x)}{g(x)}}, where {g(x) \neq 0}, then {\displaystyle h'(x) = \frac{f'(x) \cdot g(x) - g'(x) \cdot f(x)}{g(x)^2}}.
