How to enter X squared (X to the second power)?

To raise something to a power, use the

That is, to enter “X squared”, use the following syntax:

You can raise any expression to a power (just don’t forget about brackets):

`^`

character.That is, to enter “X squared”, use the following syntax:

`x^2`

.You can raise any expression to a power (just don’t forget about brackets):

`(2x+3)^4`

.
How do I enter a square root, cube root?

To enter a square root, use the

`sqrt()`

function or `x^(1/2)`

.
The second method can be used for entering a root of any power, for instance: `x^(1/3)`

– root of the third power from X (don’t forget about brackets).
How to enter a modulus?

Use the

For instance, the modulus of X can be entered as

`| |`

characters (modulus brackets) or the `mod()`

function.For instance, the modulus of X can be entered as

`|x|`

or `mod(x)`

, the result is identical.
Can I draw several graphs on a single plane?

Yes, it is possible to draw several graphs on one coordinate plane.

To do that, click on the necessary type of graph in the “Add a function graph” area (located under the first function’s input field): :

You will then see another field for entering a function (or points, if you chose the point-by-point graph type). Fill out the necessary fields and the graphs of the entered functions will be created on the same plane).
