The computation and study of Fourier series is known as harmonic analysis and is extremely useful as a way to break up an arbitrary periodic function into a set of simple terms that can be plugged in, solved individually, and then recombined to obtain the solution to the original problem or an approximation to it to whatever accuracy is desired or practical.

Fourier series make use of the orthogonality relationships of the sine and cosine functions. And, for reasons you’ll study in calculus, you can take the sum of an infinite geometric sequence, but only in the special circumstance that the common ratio r is between –1 and 1 that is, you have to have | r | < 1.įourier Series: A Fourier series is an expansion of a periodic function f(x) in terms of an infinite sum of sines and cosines. Thus, if there were a total of 28.26 squares, the area of this circle would be 28.26 cm2.īinomial Theorem: The Binomial Theorem is a quick way of expanding (or multiplying out) a binomial expression that has been raised to some (generally inconveniently large) power.Įxpansion Of Sum: You can take the sum of a finite number of terms of a geometric sequence.

If each square in the circle to the left has an area of 1 cm2, you could count the total number of squares to get the area of this circle. Straight away the drop down menu appears with the following available predefined Equations to use:Īrea Of Circle: The area of a circle is the number of square units inside that circle. Once located, we select the command Equation as shown in the image below. In this post I will describe the insert Equation in Microsoft Word 2016.įirst of all we must select the Insert tab and from the right edge of the ribbon to locate the area named Symbols as shown in the image below. The Insert Equation is available in Microsoft Word, Microsoft Excel, Microsoft PowerPoint and Microsoft Outlook. Are you a mathematical person who writes Equations? Ever needed to write an Equation in a Word Document and to present it? This is where Microsoft Office comes in.
