GeoGebra is a free on the Mac platform and cross-platform dynamic mathematics software offers all levels of education use, including geometry, algebra, tables, graphs, statistics and calculus, software in one easy to use.
Confirm expression
Always press the Enter key to confirm the expression that you enter in algebraic input.
Naming a new object
Type name = algebraic input to the new object in front of the algebraic order named.
P = (3, 2) generating point P.: Example
Denotes multiplication
You need to use an asterisk or space between the input multiplication factor.
Example: a type one or a * x ax to indicate multiplication.
Uppercase and lowercase letters
GeoGebra is case sensitive! Therefore, uppercase and lowercase letters must not be confused.
note:
Points are always named with a capital letter.
Example: A = (1, 2)
Vector designated in lowercase letters.
Example: v = (1, 3)
Segments, lines, circles, functions ... are always named with lower case letters.
Example: circle c: (x - 2) ^ 2 + (y - 1) ^ 2 = 16
The function of the variable X and the variable X and? Conic section equation always need to lowercase.
Example: f (x) = 3 * x + 2
These are the tips and tricks to bring the entire contents of GeoGebra algebraic input, hope you like!
