This video shows the viewer how to solve simultaneous equations using a graph or ‘graphing’ as it is referred to. This is done by first rearranging both equations so that y is the object of both equations. The equations can then be solved via substitution – the video does not cover this. Using graphing the next step is to plot both of the lines onto the graph. This can be done by substituting varying values of x to give the y co-ordinates. The solution to the linear equation should be the poi...
This video shows the method to write a logarithm as a sum or difference of logarithms. The square root of the term given is taken out as half according to the rule. Then the numerator and denominator is divided into product of factors. This is broken into the difference of numerator and denominator according to the rule. Finally, the product of factors is expressed as the sum of factors. Now we see the domain of the term. As the term is a square root of the term it should be greater than zero...
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.

The speaker starts out with a factored quadratic equation. The speaker goes on to do the mathematical steps necessary to find both the x and y intercepts of the quadratic function at hand. The author then continues on with the example to find the function's minimum. Next all of the points that have been solved for are plotted and the function is s...
This video shows the method to graph a linear function by finding the X and Y intercept. Only two points are needed to graph linear functions. So we find the point on Y axis or the Y intercept and the point on the X axis or the X intercept. We notice that on the Y axis the X coordinate is zero. So, we find the Y intercept by putting x=0 in the given equation and solving for y. In the same way, we find the X intercept by putting y=0 in the given equation and solve for x. We join the two points...

Don't mistake boundary walls for footpaths. A compass points to magnetic north and the top of the planet is called true north. Magnetic north is constantly moving and its position relative to true north is differen...
This video shows us how to draw a linear equation using the slope and intercept technique. First, the narrator explains how to simplify the equation in order to get the slope and intercept out. He then shows how the coefficient of x equals the slope and the constant term tells us the y position of the intercept point. The technique for drawing the final line is plotting the intercept at the right height on the y axis, then running for some distance along the x axis and rising some amount. Thi...
In this video, the instructor shows how to find the equation of a circle given its center point and a tangent line to it. To do this, take a graph and plot the given point and the tangent on that graph. Now, from the center of the circle, measure the perpendicular distance to the tangent line. This gives us the radius of the circle. Using the center point and the radius, you can find the equation of the circle using the general circle formula (x-h)*(x-h) + (y-k)*(y-k) = r*r, where (h,k) is th...
When you are solving inequality for a rational function you don't do it the same way as you would solve an equality. Now the instructor shows how to solve an inequality with the help of an example. Now to solve an inequality which is in the form a/b first take the numerator and denominator as separate equations of two lines. Now graph the two lines on coordinate axes. Using the graphs of the lines plot the intercepts of the equations on the number line noting down the sings. Now you can compa...
This video shows you how to graph an equation in standard form. In easy to understand instructions, you will learn how to find the x and y intercepts in order to put those two points on a graph, creating a line. Finding the intercepts is as easy as plugging in zero and solving for either x or y. This creates an ordered pair, which can then be graphed. The points are plotted easily on a Cartesian plane, which completes the problem.

In this video the tutor explains about the standard error of the mean. He starts explaining by drawing the diagram of a distribution and now he takes ten samples from the distribution and starts plotting them. He says that in theory if we do it infinite times then we can obtain the sampling distribution of the sampling mean. For the example he takes the number of samples as 10. Now depending on these values of n we can get different sampling distributions. Now he intends to find the mean of t...
In this video the instructor shows how to graph a line using X-Y table values. He specifies a four step approach. In the first step he picks numbers for the value of x. In the next step he substitutes the values of x in the equation of the line to obtain the corresponding y values, in the third step he plots these ordered pairs on a graph sheet. Finally in the fourth step he joins them resulting in a straight line for the given equation. This video clearly shows how to graph a line using an X...
In this video the instructor shows how to shade a system of inequalities. He says that shading a system of inequalities is similar to shading a single inequality but in the former case you tend to shade more than one inequality in the same graph. He shows how to do that using an example set of inequalities and plots the lines on the graph. He uses dotted lines for lesser than or greater than inequalities and uses straight lines for inequalities which contains the equal to symbol. Now he shade...

The camera shake method of filming is used in many popular TV shows including 'The Office,' 'Glee,' and 'Modern Family.' Typically the camera shake - or a wobbly, unstable frame - contributes a sense of urgency, unease, and interest to a shot, making it more dynamic and unpredictable. Quite like the plot of the shows mentioned above.
If you're a pee wee coach, you know that coaching kids is a tough job. Children can even be more difficult to work with than adults, but it's the best time to shape them into a great sportsman… and to get faster!
The video teaches how to convert degrees Celsius to degrees Fahrenheit. First the boiling points of 32 degrees Fahrenheit and 100 degrees Celsius are plotted on the Y and X axis. Then a line is drawn to join them both. The value m is delta Y (boiling point minus freezing point, i.e., 212-32)/ delta X (boiling point minus freezing point, i.e., 100-0). So m works out to 180/100 or 1.8. Then the formula y=mx+b (intercept of y = 32) is used, substituting X with Celsius and y with Fahrenheit, to c...
Welcome back, my hacker apprentices! In recent weeks, the revelation that the NSA has been spying on all of us has many people up in arms. I guess I take it all in stride as I just assume that the NSA is spying on all of us—all of the time. Don't get me wrong, I don't condone it, but I know the NSA.
When it comes to sniffing Wi-Fi, Wireshark is cross-platform and capable of capturing vast amounts of data. Making sense of that data is another task entirely. That's where Jupyter Notebook comes in. It can help analyze Wi-Fi packets and determine which networks a particular phone has connected to before, giving us insight into the identity of the owner.

There wouldn't be any chaos in the world without Benoit Mandelbort— chaos theory, that is. Mandelbrot, who just passed away at the age of 85, pioneered fractal geometry and greatly influenced chaos theory. He spent most of his life working in physics, biology and astronomy, and is best known for his Mandelbrot Set, a mathematical set of points in the complex plane (the boundary of which forms a fractal).
