Firemath - The Formula Editor

Examples

The examples on this page serve as a tutorial. Follow the step by step instructions and you will learn how to use the various Firemath features.

[Hint: Right-click equations and choose 'Edit in Firemath' (requires Firemath 0.8 or later)]

Example 1
β 6 3 = β 2 This is our Hello World example. Read about basic editing principles, navigation and attributes. More...
Example 2
sin⁡ x = ∑ n = 1 n odd ∞ -1 n 2 x n n ! This example contains elements like fractions, over- and superscripts. You learn how to change opening and closing characters for fences, and how to change the attributes of fractions. More...
Example 3
ℳ m n = x ∈ ℝ n x i > 0 x ∞ = m i = 1 … n Discussing this example, we quickly dive into the possibilities offered by fences. More...
Example 4
det a 0 a 0 a a = 0 , if a = 0 a 4 , else In this example we use mtables for the matrix and for the case differentiation. More...
Example 5
G⁡ β = lim n → ∞ n ! n β - 1 β β + 1 ··· β + n - 1 This is the one mouse-click example. It demonstrates Firemath's extensive keyboard support. More...
