In this video we will learn about the plotting of graphs for a pair of linear equations in two variables. Two straight lines are obtained when we plot a pair of linear equations on the graph paper ...

In this article, we will demonstrate how to use the graphing feature in the Windows calculator to try and make mathematics more fun. Microsoft has always strived to kick up a notch the Windows ...

Numbers by themselves seldom convey the big picture. Excel Charts makes it easy to illustrate trends in your business, from past expenses and profit to sales forecasts based on previous sales. T*o* ...

If you understand the definition of a mathematical function, a good way to judge it is that any line drawn parallel to the y-axis intersects with the values in the function’s curve only once. The same ...

Plot points with coordinates where \(x\) and \(y\) are equal. Three points are sufficient, but more can be plotted. Draw a line through the plotted points. If \(x\) is positive, \(y\) is negative. If ...

Quadratic graph lines are U- or Ո-shaped, which is called a parabola. A linear graph can be drawn using only three points. A quadratic graph is a curve, so more points are plotted to support accuracy.

Whether you’re a student, have a budding mathematician in your life or work in a job requiring complex graphing and computations, you likely know that a graphing calculator is a handy device. From ...

Two columns or rows of data in Microsoft Excel may contain useful information, but you'll just have a set of numbers. You can give spreadsheet viewers a graphical representation of those numbers by ...
