## Creating Your Own Equations Using the Editor

To create an equation using the editor, first of all access the equation editor.

You'll see this: This editor uses the Latex markup language. If you already know Latex, you can simply enter your equations in Latex.

If you don't know Latex, don't worry, you can use the buttons found on top of the editor. This is really easy. Once you learn how to use them, you'll be creating good-looking equations quickly, not just for your submissions, but for anything where you need equations.

I'll demonstrate how to create equations with fractions, limits, derivatives and integrals.

### Creating an Equation with Fractions

To create a fraction, click the fraction button: A menu will appear when you put the mouse over the button, but ignore it now. After you click the button you will see this: After the word frac we have two pairs of brackets. Inside the first bracket goes the numerator, and inside the second bracket the denominator. So, for example: You can see the preview there.

Now, what if we want x squared or x cubed (or any power)? We just write x followed by the symbol ^ and the power we want. For example: Now, we can turn that into an equation. I'll add another fraction by first writing + after the first fraction and clicking the fraction button again: Now, I enter the second fraction, followed by an = and another fraction: And there we have a nice looking equation.

### Saving the Equation

If you plan to use the equation on a submission or anywhere else, you need to save the equation on your computer.

To do that, simply righ-click the preview image and select "Save picture As". This will be saved as a .gif image. If the .latex extension appears, select the option of saving it as "any file" and write the .gif extension yourself.

### Creating Limits, Derivatives and Integrals

To create a limit, move the mouse over the integral button. A drop down menu will appear and select the limit button: Between the brackets input the variable. After that we usually need to write an arrow. Here we need a little trick. To input an arrow just write "\rightarrow". So, for example: After that you can write the function: To write a derivative in Leibniz notation, click the derivative button that appears when you move your mouse over the fraction button: After all that code that appears you can write the function. So, for example: To use "prime notation", simply use the prime symbol in your keyboard: Now, to create an indefinite integral, just click the integral button: Then you can input the function. For example, the integral of a fraction: If you need to use radicals, there's also a button for them: So, for example:
