$\sin^3\left(x\right)+\cos^3\left(x\right)+\sin\left(x\right)\cos^2\left(x\right)+\sin\left(x\right)^2\cos\left(x\right)=\sin\left(x\right)+\cos\left(x\right)$
$\frac{4}{3}-\frac{2}{6}$
$\lim_{x\to1}\left(\frac{1-x+ln\left(x\right)}{1+cos\left(9\pi\right)}\right)$
$\sqrt[3]{\frac{27a^3}{125b^6}}$
$\frac{\sin\left(a\right)}{1+\cos\left(a\right)}+\cot\left(a\right)=\cos\left(a\right)$
$5x^2+2x^3+x^2$
$x^2+x-1>0$
