Rafael and Zappos How To demonstrates how to pack your luggage efficiently. First, make a packing list to determine what you will need to bring on your trip. Go through your day in your mind and add things to the list accordingly. Don't forget your toiletries. Ideally bring one pair of shoes and coordinate your wardrobe accordingly. Lay out everything you will be packing and group them by like items. Don't put piles in your suitcase. Instead, roll your garment to prevent wrinkles and save spa...
ProfessorElvisZap teaches you about the laws of logarithms. When x is positive, meaning 0<x. x times y equals y times x. This is the commutative property. x times (y times z) equals (x times y) times z. This is the associative property. x times 1 equals x. This is the multiplicative property. x times x to the power of -1 equals 1. This is the multiplicative inverse property. You can use these properties with addition: a+b=b+a, (a+b)+c=a+(b+c), a+0=a and a+(-a)=0. A logarithm is a homomorphism...

In this video the author shows how to graph using an X-Y table. He shows how to do this with a sample equation. He builds a table of x, y values where he takes sample values for x like -1, 0, 1 and now he substitutes these values in the equation of the line and obtains the corresponding y values. Now finally he has an x, y value table which now he shows how to plot it on a coordinate plane. He plots all the three pairs on the graph and connects them with a line finally obtaining the resultant...

He takes an example and substitutes the values and finds out the values of the roots of the parabola. Now he substitutes these values in the equation to obtain the corresponding y coordinates. Now using these pairs of values he plots the parabola on a graph and draws it. This video shows how to fi...
In this math tutorial the instructor discusses the properties of a rhombus. He begins by saying that the properties of a rhombus are similar to the properties of a square. He says that the rhombus is a quadrilateral and hence the sum of internal angles of it is 360 degrees. He says that four sides of a rhombus are equal in length. He says that a rhombus has two diagonals which cross each other at their mid points and are perpendicular to each other but says that the lengths of diagonals are d...

In this tutorial, we learn how to graph a circle. When given an equation to graph the circle, you will first need to find the vertex of the circle. Once you find this, you can use those coordinates to mark the vertex on the graph. Follow the negatives and positives to go up, down, left, and right on the graph. Next, you will need to find the 'r' value of the equation. After this, you will use this to continue to graph the rest of the points around the vertex. When finished, draw the outline o...

This video not only gives us a good fashion tip, but it’s just plain fun to watch. The young woman has four small children, all boys and all clamoring for her attention. One of her favorite shirts looks like a maternity top but she’s had enough of that look. Her simple solution is to add a wide belt to the shirt in a coordinating color. The belt can be adjusted up or down according to the look you want. This works especially well with tops that are empire-waisted or even for maternity tops th...
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...
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 and never intersect each other. Perpendicular lines are those whose product of slopes is negative one. Perpendicular lines intersect each other and they make a perfect 90 degrees with each other at the point of intersecti...
In this video the instructor shows how to solve systems of linear equation by graphing. A system of linear equation is equations of two lines that are to be graphed on the same coordinate axes. Now take the first equation and write it to form y = mx + b. Now extract the value of slope m and graph the line as shown in the video. Similarly graph the equation of the second line as shown in the video. Now if the two lines intersect at a point, that point is the solution to the system of that line...

The video shows the explanation of greatest integer function. This video explains this with the help of graphs. The video first describes the basic greatest integer function. This means the greatest integer less than or equal to the number gave. The graph of this function is drawn. The video then shows the variations of this function. The first variation shows the function that replaces the 'x' coordinate with it subtracted by three. This shifts the graph to the right by three units. The seco...
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...

In this video the tutor shows when to use a dotted line and when to use a solid line while graphing lines in coordinate geometry. He says that we should use a dotted line to plot an inequality which contains the symbols less than or greater than. He also says that we should use a straight line when plotting an inequality which contains the signs less than or equal to and greater than or equal to. He goes on and demonstrates this idea with some examples. This video shows how to use different l...

In this video the instructor shows how to solve quadratic equation by the square root method. The square root property of equations states that if k is positive and a*a = k, then a is equal to square root of k or -1 times the square root of k. So to solve a quadratic equation by square root property first get the equation in the form of a*a = k. Now apply the square root property explained in the previous step to get the result. The instructor now demonstrates these concepts by solving some e...
