\(x^2\)


\( \frac{x}{y} \)

\(\underset{x}{\cdot}\)

\(\left\{a\\b \right\} \)

\(\require{enclose}a_{\enclose{3}}\)

 

\(e^x\)
\(x_i\)
\(\bar x\)
\(x_1+\dots+x_n\)
\(x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\)

 

\(x^2\) looks better than x^2

\(x^{y^3}\)

\(e^{x^2}\)

\(x_{i_1}\)

\(\int^{10}_1x^2dx\)

\(x_1+\cdots+x_n\)

\(\hat\mu=\bar{x}\)

 

\(e^x\)

\(e^{x^2}\)

\( x_i\)

\( x_1 + \dots + x_n\)

\mu \hat = \bar x

 

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

\(L(\lambda)=\frac{\lambda^{\sum{x_i}}e^{-n\lambda}}{\prod{x_i!}}\)

 

\int_a^b

try an equation \(x^3\) like this and 3 \(\times\) 3 = 9
and a \(\ddot x\)

\(\frac{x}{y}\)

\(\pmatrix{a&b\\c&d}\)
\(\phi \times \gamma\) = 2
\(\require{enclose} a_{\enclose{actuarial}{3}}\)

 

\(\require{enclose}\ddot {a}_{x:\enclose{actuarial}{10}}\)

 

I've uploaded a handy guide to the most useful functions here.

 

... and then used is this one.

Code:

\[
{}_{17|}\ddot{a}_{x:\annuity{n}}^{(4)}
\]

\[
{}_{17|}\ddot{a}_{x:\annuity{n}}^{(4)}
\]

 

\(
\require{enclose}
\def \annuity#1{{\enclose{actuarial}{#1}}}
\)
\annuity is defined in this post....

Code:

\(
 \require{enclose}
 \def \annuity#1{{\enclose{actuarial}{#1}}}
\)
