This tip shows how to insert an equation with trigonometric functions for example, the Euler's formula.

How to add an equation in your document, see Working with Microsoft Equation.

To insert, for example, the Euler's formula, do the following:

In the Professional presentation:

    1.    In your own equation, under Equation Tools, on the Design tab, in the Structures group, click the Script button:
