When creating exercises, you may need to use mathematical symbols in the description or question. To make this possible, you have the option to use an Equation editor ∑ or LaTeX.
Equation editor \(\Sigma\)
if you are not yet fully well-versed with LaTex, you can use an Equation editor ∑. This tool allows you to create equations. To make use of the Equation editor, follow the steps below.
- Click the domain School name in the menu on the left.
- Click label_important Courses in the menu at the top.
- Select your course or use the search bar.
- Select your assignment or use the search bar.
- Click New exercise, fill in a name and click Save.
- Click New description and select Text or click New question.
- In the text content field or the question content field, click on the Equation symbol ∑.
- Fill in your equation and click Save.
LaTeX
If you are familiar with LaTeX, it may be more time-efficient or easier to copy the LaTeX code of an equation or to type it yourself. You can find a few basic LaTeX codes written below. It may also be useful to use an external LaTeX editor, such as Visual Math Editor to help familiarise yourself with LaTeX equations. These editors offer more possibilities than the equation editor implemented in the Ans platform. To make use of LaTex, follow the steps below.
- Click the domain School name in the menu on the left.
- Click label_important Courses in the menu at the top.
- Select your course or use the search bar.
- Select your assignment or use the search bar.
- Click New exercise, fill in a name and click Save.
- Click New description and select Text or click New question.
- If you want the equation to be within the text, enter two dollar signs ($$) in the text content field or the question content field. If the equation needs to be on a separate line, use three dollar signs ($$$).
- After adding the dollar signs, enter or copy the LaTeX code.
- To add a line break in the equation, you must use shift-enter to go to the new line so that the content is in the same <div> html tag. The equation will not be formatted correctly otherwise.
- End the equation with the same amount of dollar signs as you started with. Instead of the dollar signs, you can also use \( to start the equation. Typing \ ) will make the equation end.
- Click Save and check your equation displays correctly.
Please note that the LaTeX functionality "\ begin { equation } ... \ end { equation } ", which is used to write an equation in LaTeX does not work in the Ans platform.
A few basic operations are explained in the table below. For more of these operations, click on this link which lists all functions supported by LaTeX in the math mode (math mode is in between the dollar signs), or use the Visual Math Editor as mentioned previously.
| LaTeX code | Preview |
| Plus or minus: z = x + y - 1 | \(z=x+y-1\) |
| Multiplying: x*y, x \cdot y | \(x*y,x\cdot y \) |
| Superscript: x^{2} | \( x^{2}\) |
| Subscript: x_{2} | \(x_{2} \) |
| Fraction: \frac{1}{x} | \(\frac{1}{x} \) |
| Root: \sqrt{x} | \( \sqrt{x}\) |
| Trigonometric functions: \sin{x}, \cos{x},\tan{x} | \(\sin{x}, \cos{x}, \tan{x} \) |
| Greek letters: \pi, \alpha, \beta, \delta etc. | \(\pi, \alpha, \beta, \delta \) |
