How To: Graph a parabola properly in vertex form

This video shows viewers who are interested in mathematics how to graph a parabola whose formula is displayed in vertex form, or the form y=a(x-h)^2+k, where the vertex is (h, k). After determining the vertex, plot it on your graph. After graphing your vertex, your axis of symmetry would be x= h, or the x-coordinate of your vertex. The a value in your equation will act as your slope in this case, and your should graph the two points which correspond to this slope on your plot 1 unit away on e...

How To: Use the distance formula

YAYMATH. This video is a demonstration of usage of the distance formula to find the distance between two given (x,y) points. In this video, the tutor guy who is teaching the distance formula to his students takes an example of two (x,y) points such as (5,-1) and (11,7). He then writes the distance formula on the board. The formula goes like this, the distance between two points, denoted by 'd' is equal to the square root of the sum of the square of (x2-x1) and the square of (y2-y1) where (5,-...

How To: Carve a net needle out of wood

Carving a net needle from wood is probably easier than you think as long as you have your trusty Swiss army knife at hand. It has a wide array of available tools in a small unit. First you will need a piece of balsa wood. It should be 1/8 of an inch thick by 3 inches wide and 8 inches tall. Using the sharp narrow blade of the knife, you will cut 3 reference holes in a triangular pattern. The points of the triangle should be 1 inch apart at the bottom and the triangle should be 2 inches high. ...

How To: Do Celsius to Fahrenheit temperature conversion

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...

How To: Fold a basic paper airplane

In this tutorial, we learn how to fold a basic paper airplane. First, fold the paper in half and make a crease. Next, unfold it and then line the corners with the middle line you just made on one side of the paper. From here, you will fold the paper down until you reach as long as the crease can go. Next, take the point on the side and fold it an inch over next to the point. Then, repeat this on the other side, touching the other point in the middle. Now, take the tip and fold it over. From h...

How To: Determine if a point lies on a line in standard form

In this video, we learn how to determine if a point lies on a line in standard form. In order to do this, you will need to substitute the X and Y value with the ordered pair that is given. The X value is the first number and the Y value is the second number. Re-write your equation, substituting in the numbers to the appropriate spots. Now, simplify the equation by doing multiplication with the negatives and positives (if given). When you get through the equation, you will end up with the solu...

How To: Draw an isosceles trapezoid

This is a video tutorial in the Education category where you are going to learn how to draw an isosceles trapezoid. This video demonstrates how to draw an isosceles trapezoid with a long base (B), a short base (b) and a 35 degree angle. First you draw the long base. Now center the short base at the center point of the long base and mark the end points of the short base with dots. Next draw perpendicular dotted lines from the dots extending upwards. Draw 35 degree angles from either end of the...

How To: Use the distance formula for two points

In this tutorial, we learn how to use the distance formula for two points. The distance formula is D= the square root of (X2-X1) squared, plus (Y2 minus Y1) squared. It may look confusing, but it's just a derivation of a theorem. First, find the two points that you have and graph them. If you want to know the distance between them, you cannot just count squares if it's a diagonal line. If you remember geometry, you can draw a right triangle over the line to figure out the distance. After this...

How To: Play Farkle with dice

This video teaches you how to play the dice game Farkle. You will need 6 dice and a pen and paper to keep score with. The scores are as follows: 1(on the dice)= 100 points, 5(on the dice)= 50 points. A triple of any dice number is worth the number on the dice times 100. With the exception of a triple of one which equals 1000. A triple pair is also equal to 1000. (i.e., a pair of ones, a pair of threes and a pair of fives). A straight is consecutive numbers such as 1,2,3,4,5,6 which results in...

How To: Use and find x & y-intercepts in algebra

A straight line can be represented in the form of a liner equation containing two variables x and y. When the equation is graphed on a pair of coordinate axes, the line passes cut through the axes in two points. The point where the line cuts the x-axes is called as its x coordinate and the point where the line cuts the y-axes is called as its y coordinate. In this way a line has x-intercept and y-intercept. The x-intercept of a line lies on x axes and is in the form (a,0). Similarly the y-int...

How To: Find coordinates (ordered pair)

This video tells you how to identify the coordinates of an ordered pair from a given point. An ordered pair is denoted by (x, y). Normally a graph has two axis, the x and the y axis. Consider a point on the graph. It will surely be the intersection of two values and one value will be from the x axis and the other valve from the y axis. Find the two corresponding values of the given intersection point. The value on the x axis will be x and the value from the y axis will be y. Now you have got ...
