This video explains the properties of parallel lines and transversals in geometry. The instructor, Robert Ahdoot, uses an analogy in which he compares lines and transversals to the streets of Manhattan, New York. Continuing with this comparison, he goes over corresponding angles of two parallel lines cut by the same transversal, also explaining when they're equal. He then shows where interior and exterior angles may be found, and then goes over whether two angels are same-side or alternate, d...
In this video the instructor shows how to compute percentage problems. Percentage was first used in ancient Rome when the emperor Augusts levied a 1/100 of a tax on goods sold. To solve percentage problems you need to know how to convert between percentages and decimals. When you have a value in decimal, to convert it into percentage, shift the point two decimals to the right. To convert from percentages to decimals, shift the decimal two places to the left. For example to convert .50 to perc...
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...
This video demonstrates the process for drawing prospective shadows using a light source. Start with the shadow vanishing point which is directly below the light source on the horizon line. Draw lines from the shadow vanishing point to the front three corners of your box. Next draw lines from your light source to the top three corners of your box. Where the shadow lines intersect, that area defines the shadow area and can be filled in for shadows. The shadows, of course, will line up with you...
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 an example. He then shows you how to find the slope-intercept form from the point slope form. Finally, he shows you how to graph the line using both of the equations. He shows you how to find the equations with different...
In this video the instructor shows how to sketch the graph of x squared and square root of x. The first equation is the x squared which is y = x * x. Now to sketch this take a sample values of x and substitute in the equation to get the value of y. Similarly find the set of points for the equation. Finally plot these points and sketch this graph which is in the form of a parabola. The curve is in the form of alphabet 'U' with its vertex at the bottom. Now similarly take the square root of x e...
Without good navigational skills, your expedition could lead to failure or result in a dangerous situation. Try to use a laminated map which is better in wet conditions. 1:25,000 scale maps provide the greatest detail. One grid square equals 1 kilometer. Use map keys for reference. 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 the way to name a line segment. A line segment begins and ends with an end point. We can name a line segment by naming the two end points of the line segment. The example shown in the video shows a line segment that ends with points named 'A' and 'C'. So, we can name this line segment as segment 'AC'. This can also be named as segment 'CA'. The example shown consists of a point 'B' in between 'A' or 'B'. We cannot name the line segment as segment 'AB' or 'BA' and segment 'BC'...
In this video the instructor shows how to derive a general equation for a line in Point-Slope form. The slope of an equation is the ratio of difference of y coordinates to the difference of x coordinates. In other words, slope is the change of y up on change of x. So you have the basic slope equation m = (y2 - y1)/(x2 - x1). When you have fractions you can simplify them by multiplying the denominator to the numerator on both sides. So multiply the equation by (x2-x1) on both sides. This gives...

Street artist wackojacko54321 teaches you how to draw "wild style" graffiti. There is no definite technique or way of drawing wild style. Wackojacko54321's interpretation involves starting with a simple piece with connecting letters (of which he provides an example) and possibly arrows. Add more basic arrows and connections to unify the piece more. Connection points of the arrows are important. Attach them to the ends/corners of letters or other letters/connections. Spice it up with more adva...
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 tangent line is exactly the same as the derivative definition, an easier way to find the tangent line is to differentiate using the rules on the function f. For example, Find the slope of a line tangent to the function ...

If you watch this video, you will learn what slope is, and how to find it. Slope is defined as rise divided by run, where rise in the increase the Y coordinate and run is the increase in the X coordinate. For example, if you pick two points, you can travel from the left point to the right point. However many points you go is the run. How far up you go is the rise. For example, if your rise is 4 and your run is 2, then you divide 4 by 2 to get your slope, 2. When you're finding the rise, if yo...

Three point lighting is the key to MAKING videos look professional. Tom Skowronski, the associate editor of Videomaker, guides us through the process of three point lighting. Three point lighting involves the use of three types of light to create a professional appearance when video taping. First, a key light is used to provide bright illumination of the subject. Then, a fill light cleans up the dark areas on the face. Lastly, a backlight fills serves to separate the subject from the background.
