In this video tutorial, viewers learn how to graph a linear equation. The linear equations example used in this video is y= 1/3x-3. The equation to graph a linear equation is y= mx+b. Now substitute each number into the equation. Therefore, m= 1/3 and b= -3. Begin by graphing ...more
In this video the instructor talks about parallel and perpendicular lines. Parallel lines are lines whose slope is the same. Now take the equations of a couple of parallel lines. Graph those lines on a coordinate axes and you can see that the lines are parallel to each other a ...more
This video shows how to find the formula of a piecewise function when given a graph. The first step is to write a definition for the graph, which is done by identifying the different domains shown in the graph. The second step is writing formulas for each domain specified by t ...more
This is a mathematical instructional video on finding the point slope form of a line equation. This technique allows you to find the x and y intercepts of a line. The point slope form is (y-y1)=m(x-x1). The instructor tells you what each of the variables represents, and shows ...more
This is the video about how to find the equation of a tangent line. As you may recall, a line which is tangent to a curve at a point a, must have the same slope as the curve. Therefore, the slope of the tangent is m = lim f(a + h) - f(a) h-->0 h Since the slope equation of the ...more
In this math lesson you will learn how to graph linear inequalities. Let’s graph the following inequality: 4x + y > 4 First, attach the corresponding equation: 4x + y = 4 Then, isolate y by subtracting 4x on both sides: y = -4x + 4 The slope and y-intercept equation of a ...more
TouchDevelop is a browser-based programming tool that allows anyone to build your own Windows 8 apps directly from any touchscreen device, including iPad, iPhone, Windows Phone, Android, PC and Macs. Once the script is created and the app proves to work, it can be placed in th ...more
It's been a long time coming, but Apple Maps finally has cycling directions for your iPhone. Google Maps has had cycling support for ten years now, though, many of its more useful features had been incorporated within the last few years. Well, with iOS 14, Apple has caught up, ...more
Android's stock battery menu is pretty decent. You can see which apps have been using the most power, and you can tell when your CPU was awake or asleep, among other things. But a lot of times, battery-sucking services will get lumped under the generic "Android System" header, ...more
As a long-distance runner off and on for the past, I absolutely detests hills. While there are many apps that can measure elevation and slope for certain routes, understanding spatial data on a line graph or even an elevation map can be difficult. A solution arrives by way of ...more
