    1. Quadratic formula

    x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}


    x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}

    2. Integrals

    \int_a^x \int_a^s f(y)\,dy\,ds<br />
 = \int_a^x f(y)(x-y)\,dy


    \int_a^x \int_a^s f(y)\,dy\,ds
    = \int_a^x f(y)(x-y)\,dy

    3. Fractions

     \frac{1}{2} or \tfrac {1}{2}


    \frac{1}{2} or \tfrac {1}{2}


    4. Array

    \begin{array}{|c|c||c|} a & b & S \\<br />
\hline<br />
0&0&1\\<br />
0&1&1\\<br />
1&0&1\\<br />
1&1&0\\<br />
\end{array}


    \begin{array}{|c|c||c|} a & b & S \\
    \hline
    0&0&1\\
    0&1&1\\
    1&0&1\\
    1&1&0\\
    \end{array}

    5. Midpoint Formula

    M = \left( \frac{x_1 + x_2}{2}, \frac{y_1+y_2}{2}\right)


    M = \left( \frac{x_1 + x_2}{2}, \frac{y_1+y_2}{2}\right)

    6. Slope Formula

    \frac{y2-y1}{x2-x1}

    \frac{y2-y1}{x2-x1}

    7. Distance Formula

    M_1M_2 = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}


    M_1M_2 = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
