- [Narrator] When you create formulas in Mathematica 11 Notebooks, there will be times when you want to type them in directly. Then there are other times when you might want to make the formulas a bit more readable by rendering them typographically. In this movie, I will show you how to create formulas that are easier to understand visually, using the Math Assistant. I have opened a blank Mathematica notebook, and what I want to do is display the Math Assistant. To do that, I will open the Palettes menu, and then click Basic Math Assistant.
The Basic Math Assistant appears over on the right-hand side of the screen, and you can see that there are a number of sections. It opens to Typesetting, or at least my copy of it did. You can also display a calculator, which allows you to enter in various equations, or various calculations, the way you would on a calculator. There's the Basic and Advanced tabs, and I'll close Calculator by clicking on its title bar. Then there are Basic Commands, where you can enter in mathematical constants, you have pi, e, i, infinity, phi, and so on.
And there are various tabs, so you have Algebra, Expressions and Equations, Linear Algebra and Matrices, and so on. What I'd like to do, though, is to show how to use the Typesetting section. So you see here that we have subscripts and superscripts, as well as roots, so we have here the cube root, or we can make it any root we want, square root, and so on. Let's say that I want to find the cube root of a particular value. To do that, I will click on the Typesetting forms tab, if it's not already displayed, and then click radical, which is one, two, three, four, five, six from the left or three from the right in the top row.
So I'll click that, and you can see that it has been entered in the notebook. So I'll go over to the notebook, and I will click in the top box. This indicates the root that I want to take. I'll type in three, indicating the cube root, and then I'll press tab, which highlights the box inside of the radical sign, and I'll type 64. So what I'm doing is finding the value that, when multiplied three times, will result in 64.
And when I press Shift + Enter, I see that value is four. Four times four is 16, times four once again is 64, so I know the answer is correct. When I'm done using the Basic Math Assistant, I can go over to where it is, click its title bar, click the close button, and I'm done.
