This module presents step-by-step instructions for creating, and then editing well-known formulas to illustrate how to use the editor. The example and what properties of the editor it illustrates are listed below. All of these assume you have a blank Math Editor open.
As a simple example, we'll step through several ways of writing the well-known Quadratic Equation (with real or complex coefficients):
Probably the quickest way to enter math is by using the keyboard. This method requires entering a total of 3 statements and a few Tab key presses.
a*x^2+b*x+c=a*(x-(-b+root)/(2*a))*(x-(-b+root)/(2*a))
". See below for
details .Most of the text in step 2 should look similar to the notation used in calculators, except for "
root
". Many calculators follow different conventions for entering complicated math operations like integrals and vectors. For this version of the editor we decided to wait for feedback from users on which convention to adopt. Until one is chosen, any math element defined in the W3C MathML Specification can be entered. The toolbar also provides a way to see the available commands.
b^2-4*a*c
" into the empty block under the radical.Now, the equation should be complete. In the previous steps we used the Tab key to navigate to empty blocks that still needed information in them, skipping over optional ones. We used Shift+ arrow keys to select math and Ctrl+C and Ctrl+V to copy and paste that math.
