10 [WikiPlugin|Help:WikiPlugin] to display mathematical formulae in a Wiki page.
15 <?plugin TeX2png text="$$(a+b)^n=\sum_{k=0}^n{n\choose k}a^k b^{n-k}$$" ?>
20 <?plugin TeX2png text="$$(a+b)^n=\sum_{k=0}^n{n\choose k}a^k b^{n-k}$$" ?>
23 There is only one argument which is the text of the mathematical
24 expression. This text *must be* enclosed by a dollar $ within a
25 paragraph or two dollars $$ on a separate line. In the last case,
28 To write mathematical formulae, the syntax is the one
29 of [LaTeX | http://www.latex-project.org].
33 This plugin is only to produce readable mathematical formulae. Any
34 other text is not allowed : so if an expression is not enclosed by
35 dollars then it will be displayed by a red text. It is all the same
36 possible to display raw text as <?plugin TeX2png text="$\textrm{\LaTeX}$" ?> by using :
39 <?plugin TeX2png text="$\textrm{\LaTeX}$" ?>
42 This plugin is not able to produce sophisticated mathematicals texts
43 with links, cross references... For that, you can use for example
48 Some Greeks letters : <?plugin TeX2png text="$\alpha$" ?>, <?plugin TeX2png text="$\beta$" ?>, ... and a formula <?plugin TeX2png text="$\sum_{i=1}^n \frac1{i^2}=\frac{\pi^2}{6}$" ?> to test display in a paragraph.
50 *Exercise 1* Consider the function <?plugin TeX2png text="$$f(x)=(x^2-4x+3)^{1/2}$$" ?>
52 #Give the largest real domain for which f(x) is well defined.
53 #Give a domain on which the function is one-to-one. Using this domain derive a formula for the inverse function <?plugin TeX2png text="$f^{-1}(x)$" ?>.
54 #Calculate the derivative f'(x).
56 *Exercise 2* Consider the function :
58 <?plugin TeX2png text="$$f(x) = \int_0^x e^{-t^2}\,dt, x\in\mathbb R$$" ?>
60 #Show that for all r > 0 :<?plugin TeX2png text="$$\frac{\pi}{2}\int_0^r t e^{-t^2}\,dt \leq \int_0^r e^{-x^2}\,dx \int_0^r e^{-y^2}\,dy \leq \frac{\pi}{2} \int_0^{\sqrt{2} r} t e^{-t^2}\,dt$$" ?> *Help* : you can use polar coordinates.
61 #Hence find the limit of <?plugin TeX2png text="$f(x)$" ?> as x tends <?plugin TeX2png text="to $\infty$" ?>.
