If you have somewhere a very long formula, please share it with us. This will save time for everybody!

## Design-Tip

• A space before the formula leeds to the box around the line.
• Don't hesitate it is not looking so good. That can be done by anybody else.
• An easy solution to get the same look is to copy the lines of an other formula for you formula.

## Formulas

m=\frac{y_2-y_1}{x_2-x_1}


m=\frac{y_2-y_1}{x_2-x_1}
