Zgjidh cos^2x(tan^2x+1)=

$$\cos ^ { 2 } x ( \tan ^ { 2 } x + 1 ) =$$

Vlerëso

$$\left(\cos(\frac{x}{\left(\cos(x)\right)^{2}})\right)^{2}$$

Diferenco në lidhje me x

$$-\frac{\cos(x\left(\left(\tan(x)\right)^{2}+1\right))\left(4\sin(x)\left(\cos(x)\right)^{3}\cos(x\left(\tan(x)\right)^{2})+4\cos(x)\left(\sin(x)\right)^{3}\cos(x\left(\tan(x)\right)^{2})+\left(\sin(2x)\right)^{2}\sin(x\left(\tan(x)\right)^{2})+4\left(\cos(x)\right)^{4}\sin(x\left(\tan(x)\right)^{2})+8x\left(\sin(x)\right)^{2}\cos(x\left(\tan(x)\right)^{2})+4x\sin(2x)\sin(x\left(\tan(x)\right)^{2})\right)}{2\left(\cos(x)\right)^{3}}$$
