$6x^4+2x^2-8=0$
$\int_1^{\infty}\left(\frac{ln\left(x\right)}{x^{-3}}\right)dx$
$\left(cos^2\left(x\right)-1\right)\left(csc^2\left(x\right)-1\right)=-cos^2\left(x\right)$
$\frac{x+2}{3}>x+1$
$\left(2x^{4\:}y+4z\right)\left(2x^4y-4z\right)$
$2\left(-1\right)^{2}-3\left(-1\right)+4$
$8cos\left(x\right)\left(e^{2y}-ye^y\right)\left(\frac{dy}{dx}\right)=6e^ysin\left(2x\right)$
