If it is just to get the square x i would recommend just using the square component.

If it is to create a larger equation then you can add it as a panel or by double clicking the function.

To create a square x function you can use it as Pow(x,2) or any variable you would like to use as 2.

This a bug in the way draw full names works with expressions. Just rename the input without any spaces

when you write your equation, make sure that the input variable name is the same as they variable in the equation

I'm sorry, but I don't understand what it means, could you send me a image, please? Because I try everything: I follow the Arturo Tedeschi's book, I did the examples above, but, anything doesn't works, and I did using the component "Square" and works, but now I need to do other expression using this, but simply the function in the component "Panel" -((x2+y2)/4)+4 and don't work too. So, the question is: How could to use the "Evaluate" with a expression (in Panel or not)? Thank you so much!

Can you upload the file with the failing expression?

Incidentally the text you posted just uses the regular 2 character, not the superscript ² which is needed for squaring.

Also note you can just use x*x or x^2 to square x.

I tried x^2, but don't works. I'll try x*x
