Writing Mathematical Formulas in Word and PowerPoint Documents

First, you need to install the Mathematics add-in:

Word (most versions):

Word 2013:

After downloading and installing the add-in, you should see additional Tab in your Word:
Pressing on the “Equation” button will open equation editor with many different options and palettes (there is also very convenient shortcut keystroke “Alt- =”):
Make sure that you play enough with this add-in to learn it well. In the homework, you’ll need to write matrices, upper and lower indices, equations, different symbols, Greek letters, etc. If you cannot find some symbol or formula, you could always use hand drawing of any formula by clicking on “Ink Equation”.

For additional information:

Another option is to use MathType:

This product is much more comprehensive and convenient to use, though it has two main disadvantages. First, it is not free (discounts are available) and only 30-day trial is available. Second, if you want to change the font size in your document, then you need to reopen every typed formula and to change the font size inside the MathType editor.

Differential Geometry for Beginners: Books Review

Differential geometry can be successfully used in many areas of study from special relativity to image processing. I’m looking for books explaining the differential geometry to the engineer with basic linear algebra / calculus knowledge. I don’t need it to be rigorous, or formal. I have no intentions to be a mathematician, thus the proofs needed only if they are constructive, or they help to understand the motivation and theory. I want to see intuitive tools, to understand the terms used in the theory, and to get insights in visual geometric terms.
