sec^2θ-2/cosθ+sinθ хәл итегез

$$\frac { \sec ^ { 2 } \theta - 2 } { \cos \theta + \sin \theta }$$

Исәпләгез

$$\frac{\sin(\theta )-\cos(\theta )}{\left(\cos(\theta )\right)^{2}}$$

θ аерыгыз

$$\frac{-4\sin(\theta )\left(\cos(\theta )\right)^{3}+4\left(\cos(\theta )\right)^{4}+4\left(\sin(\theta )\right)^{2}-2\left(\cos(\theta )\right)^{2}+3\sin(2\theta )}{2\left(\sin(\theta )+\cos(\theta )\right)^{2}\left(\cos(\theta )\right)^{3}}$$
