$\frac{\sec\left(x\right)}{1+\cos\left(x\right)^2}=0$
Learn how to solve equations problems step by step online. Find the roots of sec(x)/(1+cos(x)^2). Find the roots of the equation using the Quadratic Formula. Multiply both sides of the equation by 1+\cos\left(x\right)^2. Take the inverse of \sec\left(x\right) on both sides. Apply the formula: \mathrm{arcsec}\left(\sec\left(\theta \right)\right)=\theta .
