Exercise/Example Template

For an exercise (and perhaps example) you want the reader to have access to the solution, but to not see it immediately. This template allows you to hide the solution.

You can use

What is 1+1?
Solution:
</div><div class="NavContent" style="text-align:left">
2
</div></div><div class="NavEnd"> </div>


to make:

What is 1+1?

Naming Equations and Referring to Them

You can name (or number) and refer to equations using

Thus we have
{{NumBlk|:|$y_{n+1}=y_n+h(a_1k_1+a_2k_2) \,.$|{{EquationRef|method}}}}
From ({{EquationNote|method}}), we see ...


to make:

Thus we have

${\displaystyle y_{n+1}=y_{n}+h(a_{1}k_{1}+a_{2}k_{2})\,.}$

(method)

From (method ), we see ...

LU decomposition is

 A name of the algorithm to solve any linear systems a matrix decomposition which writes a matrix as the product of a lower triangular matrix and an upper triangular matrix A the program to solve any linear systems None of those

2

 The determinant of ${\displaystyle \left[{\begin{array}{c c}3&4\\2&1\end{array}}\right]}$ is .

 ${\displaystyle \displaystyle \ y_{1}=}$ ${\displaystyle \displaystyle \ y_{2}=}$ ${\displaystyle \displaystyle \ y_{3}=}$ Next, we have Ux = y ${\displaystyle {\begin{bmatrix}2&-1&3\\0&4&-5\\0&0&6\end{bmatrix}}}$ X ${\displaystyle {\begin{bmatrix}x_{1}\\x_{2}\\x_{3}\end{bmatrix}}}$ = ${\displaystyle {\begin{bmatrix}y_{1}\\y_{2}\\y_{3}\end{bmatrix}}}$ Use backward substitution we have: ${\displaystyle \displaystyle \ x_{1}=}$ ${\displaystyle \displaystyle \ x_{2}=}$ ${\displaystyle \displaystyle \ x_{3}=}$
