2 | <h3>How to write mathematical formulas in your exercises.</h3> |
||
3 | |||
4 | You may embed mathematical symbols and formulas into the statement (when it |
||
5 | is of html format), hint and solution. |
||
6 | <p> |
||
7 | If you simply want to insert some mathematical symbols or greek letters, |
||
5903 | bpr | 8 | you just need to type a <span class="tt wims_code_words">\</span> followed by the name of |
4427 | bpr | 9 | the symbol or greek letter (if you have not used this name in your parameter |
5903 | bpr | 10 | definitions). For example, <span class="tt wims_code_variable">\pi</span> gives you $m_pi, |
11 | <span class="tt wims_code_variable">\le</span> gives $m_le, <span class="tt wims_code_variable">\pm</span> gives $m_pm, <span class="tt wims_code_variable">\rightarrow</span> gives |
||
23 | reyssat | 12 | $m_rightarrow, etc. The names of the symbols follow the standard TeX |
13 | convention. Here is a |
||
14 | !href target=wims_help module=help/wimsdoc.en&subject=mathfonts#mathfonts list of mathematical symbols and their names |
||
5903 | bpr | 15 | (replace <span class="tt wims_code_words">$$m_</span> by <span class="tt wims_code_words">\</span> in the names). |
23 | reyssat | 16 | <p> |
17 | More generally, to insert a whole mathematical formula, you |
||
18 | can type the formula in the usual way as if you enter it into any |
||
19 | mathematical software or any computational tool under WIMS. In order to make |
||
20 | the formula formatted and shown beautifully, you have |
||
21 | only to enclose it in a pair of parentheses preceded by a backslash \. For |
||
5903 | bpr | 22 | example, <span class="tt wims_code_words">\(x^3-3x+cos(2pi*x)^5)</span> gives you |
23 | reyssat | 23 | !insmath x^3-3*x+cos(2pi*x)^5 |
5903 | bpr | 24 | , or <span class="tt wims_code_words">\(sqrt(x^2+y^2))</span> gives you |
23 | reyssat | 25 | !insmath sqrt(x^2+y^2) |
5903 | bpr | 26 | . You can type <span class="tt wims_code_words">\(integrate(x^2+1)dx)</span> for |
23 | reyssat | 27 | !insmath integrate(x^2+1)*dx |
5903 | bpr | 28 | , or <span class="tt wims_code_words">\(integrate(exp(x^2+1),x=1..infinity))</span> for |
23 | reyssat | 29 | !insmath integrate(exp(x^2+1),x=1..infinity) |
30 | . You can also write the sum |
||
31 | !insmath sum(1/n^2,n=1..infinity) |
||
5903 | bpr | 32 | using <span class="tt wims_code_words">\(sum(1/n^2,n=1..infinity)</span>, or the product |
23 | reyssat | 33 | !insmath product(n/(n+1),n=1..infinity) |
5903 | bpr | 34 | using <span class="tt wims_code_words">\(product(n/(n+1),n=1..infinity)</span>. |

36 | More helps on how to enter mathematical expressions are in |
||
37 | !href target=wims_help module=help/main&chapter=1&open=1_math#math this page |
||
38 | . |
||
39 | <p> |
||
40 | To show a matrix |
||
41 | !insmath [1,2,3;4,5,6;7,8,9] |
||
5903 | bpr | 42 | , you should type <span class="tt wims_code_words">\([1,2,3;4,5,6;7,8,9])</span>. Nested matrices are |
23 | reyssat | 43 | accepted (and will be rendered correctly). |
44 | <p> |
||
45 | For experts in TeX or LaTeX, please notice that whenever the software sees a formula |
||
5903 | bpr | 46 | enclosed in a pair of parentheses preceded by <span class="tt wims_code_words">\</span> which contains |
23 | reyssat | 47 | backslashes, it will interpret it as a TeX source, and will directly try to |
48 | format it by TeX. This will allow you to write very sophisticated formulas if |
||
49 | you know how to write them in the TeX way. |
||
5903 | bpr | 50 | TeX ou LaTeX, you can write inside the parentheses <span class="tt wims_code_words">\displaystyle</span> or |
51 | an empty pair of braces <span class="tt wims_code_words">{}</span>. |
||
280 | reyssat | 52 | For example, you will get |
242 | bpr | 53 | !insmath \displaystyle a |
5903 | bpr | 54 | via <span class="tt wims_code_words">\(\displaystyle a )</span> |
55 | or <span class="tt wims_code_words">\({} a )</span> |
||
242 | bpr | 56 | and |
57 | !insmath a |
||
5903 | bpr | 58 | via <span class="tt wims_code_words">\( a )</span>. |
242 | bpr | 59 | |
23 | reyssat | 60 | <p> |
61 | And the most complete way to use TeX in your exercise is to choose |
||
62 | !href cmd=help&special_parm=format TeX format |
||
63 | (for the statement only). |
