Text

With this mode you can create texts or L^ATEX formulas.

1. Clicking on the drawing pad creates a new text at this location.

2. Clicking on a point creates a new text whose position is relative to this point.

Afterwards, a dialog appears where you may enter the text. It is also possible to use object's values and thus create dynamic texts.

Input	Description
''This is a text''	simple text
''Point A = '' + A	dynamic text using the value of point A
''a = '' + a + ''cm''	dynamic text using the value of segment a

The position of a text may be absolute on the screen or relative to the coordinate system (see properties of the text, 3.1.1).

L^ATEX Formulas

In GeoGebra you can also write formulas. To do so set the check box for a L^ATEX formula in the dialog of the text mode and enter your formula in L^ATEX syntax. Here, some important L^ATEX commands are explained. Please have a look at any L^ATEX documentation for further information.

LATEX input	Result
a \cdot b	a . b
\frac{a}{b}	${\frac{{a}}{{b}}}$
\sqrt{x}	$\sqrt{{x}}$
\sqrt[n]{x}	$\sqrt[n]{{x}}$
\vec{v}	$\vec{{v}}\,$
\overline{AB}	$\overline{{AB}}$
x^{2}	x2
a_{1}	a1
\sin\alpha + \cos\beta	sin$\alpha$ + cos$\beta$
\int_{a}^{b} x dx	$\int_{{a}}^{{b}}$xdx
\sum_{i=1}^{n} i^2	$\sum_{{i=1}}^{{n}}$i2
