## Microsoft Mathematics Tutorial 4 – Plotting Graphs

This is the fourth tutorial of the Microsoft Mathematics Tutorial Series.

In this tutorial, we learn how to plot 2 and 3 dimensional Cartesian graphs and 2 dimensional polar graphs.  We also learn how to modify the settings of the Graphing window such as plotting range and proportional display.

1. Open Microsoft Mathematics.

2.  Select the Graphing tab.

2. Under Equations and Functions, be sure that 2D and Cartesian are selected.

3. Type $y = x^2 + 2x - 3$ and $y = 3x$. Use the ^ symbol for exponent.

4. After the equations have been entered, click the Graph button. » Read more

## Microsoft Mathematics Tutorial 3 – Equations and Inequalities

This is the third tutorial of the Microsoft Mathematics Tutorial Series.  The first tutorial is about the Introduction to the User Interface and the second tutorial is about Peforming Basic Numerical Computation.

Aside from being a scientific calculator, Microsoft Mathematics is also a computer algebra system.  It is capable of simplifying or expanding expressions, solving equations and inequalities, and performing other algebraic manipulations.  In this post, we discuss some of the most used commands in solving equations and inequalities used in high school mathematics.

To try the examples below, open Microsoft Mathematics and be sure that you are on the Worksheet tab.

Solving Equations

To solve the equation $2x - 3 = 5$, type 2x – 3 = 5 in the Input text box and then press the ENTER/RETURN key on your keyboard. The output of the command is shown below.

Notice that tirst, the input was reformatted to solve (2x – 3 = 5, x) and second, the solution is shown at the bottom. The Solution steps, a link which can be expanded, is also shown. Microsoft Mathematics is capable of generating solution steps with complete explanation to some algebraic problems. Clicking the Solution steps link will show the figure below.  » Read more

## Microsoft Mathematics Tutorial 2 – Performing Basic Computations

This is the second tutorial in the Microsoft Mathematics Tutorial Series.  In this tutorial, we learn how to perform basic mathematical computation using Microsoft Mathematics.

There are three parts of Microsoft Mathematics used in numeric  computations: the calculator pad (green box) where the command buttons are located, the input box (yellow box) where the commands are typed, and the output boxes where the input, the step by step computations (if applicable), and the output of the computations are displayed. The input text box and the output boxes are located in the Worksheet tab.

Open Microsoft Mathematics to perform the computations below.  » Read more
