$\displaystyle\frac{4x^2+12yx+9y^2}{3y+2x}$
$x^2-x+1=0$
$4x-1>5$
$\displaystyle\tan\left(x\right)+\cot\left(x\right)=\sec\left(x\right)\cdot\csc\left(x\right)$
$\displaystyle\frac{\sin\left(x\right)}{\sec\left(x\right)+1}+\frac{\sin\left(x\right)}{\sec\left(x\right)-1}=2\cot\left(x\right)$
$\displaystyle\frac{\cos\left(x\right)^2-\sin\left(x\right)^2}{\cos\left(x\right)+\sin\left(x\right)}=\cos\left(x\right)-\sin\left(x\right)$
$\displaystyle\lim_{x\to 5}\left(\frac{x^2-25}{x-5}\right)$
$\displaystyle\lim_{x\to 3}\left(\frac{2x^3-5x^2-2x-3}{4x^3-13x^2+4x-3}\right)$
$\displaystyle\lim_{x\to a}\left(\frac{\sqrt{b^2-x}-\sqrt{b^2-a}}{x-a}\right)$

$\displaystyle\int\frac{2x^3-1}{x^4+x}dx$
$\displaystyle\frac{1}{y}\cdot\frac{dx}{5x\sin\left(y\right)}=ydy$
$\displaystyle\frac{dy}{dx}=\frac{3x^2+4x+2}{2\left(y+1\right)}$
$\displaystyle y\cdot\frac{dx}{\left(y+9\right)}\cdot\left(y+1\right)=\frac{dy\cdot\left(x+6\right)}{xy}$
