$$ z = 2a + 3y $$
$$ M(s)<M(t)<|M| = m $$
$$ y'' = c\{f[y',y(x)] + g(x)\} $$
$$ x^2 \ a_n \ x^n_i $$
$$ \sum_{i=1}^n \int_a^b $$
$$ A = \begin{bmatrix} a_{11} & a_{12} & \cdots & a_{1n}\\ a_{21} & a_{22} & \cdots & a_{2n}\\ \vdots & \vdots & \ddots & \vdots \\ a_{m1} & a_{m2} & \cdots & a_{mn} \end{bmatrix} $$
