In this tutorial, the author shows how to determine if a point lies on a given line which is in Point Slope Form. To show the method he takes a sample point order pair and an equation of a line in its point slope form. Now he substitutes the value of the x, y order pair and the equation of the line, and solves the equation on both the sides. If both sides match it means that the point lies on the given line, or else it does not lie on the current line. In this video, the instructor shows how ...
This is a tutorial about how to prove the congruency (equality) of two triangles when the values of two angles and an included side of each triangle is given. The author of this video instructs the viewer that it should be first determined whether the values of two angles of one triangle are the same as those of two angles of the other triangle. Then one must seek to determine the equality of sides included in those angles in both the triangles. When it is found that these three values in one...
Welcome back, my budding hackers! Recently, I showed you how you could exploit the widely disseminated OpenSSL vulnerability that has to become known as "Heartbleed".

In this tutorial, we learn how to determine if lines are parallel or perpendicular. You will be given two straight line equations. First, remember that parallel lines have equal slope, identical to each other. Perpendicular lines have negative reciprocal slopes. For example, 2/3 and -3/2 would be a perpendicular line. If you think of parallel lines, then you can graph them to see what they look like when written down. Then, graph the other lines to see what they look like as well. Once you un...

If you have an equation with an equivalent fraction, you will first multiply the first numerator by the second denominator. Then, you will divide this answer by the denominator of the first fraction. After you do this, it will give you the correct answer. You can also do the reverse multiplication for this to check your answer and make sure you are correct. You can get an answer no matter what the numbers in the equ...

This video shows you how to milk a cow with your bare hands. Wipe the udder with alcohol based wipes, to make sure it is clean. Place your stool at the side of the cow, towards the back end. Remove a little wax from the teats before starting. Squeeze the teats firmly with a regular motion. A cow should be milked twice a day. If the udder is pendulous then use a flatter pan rather than an milking bucket. The richness of the pasture will determine how much milk the cow delivers. Rainfall and th...
Viewers learn that a net is the shape formed by "unfolding" a 3-dimensional figure, so a net shows all the faces that make up the surface area of the figure. Viewers are then asked to determine what type of 3-dimensional figure can be made from a given net (note that a cylinder has 2 circular bases, a pyramid has triangular faces, a cone has 1 circular base, and a prism has rectangular faces). Students are also asked to determine if a given net can be used to make a cube. This video will bene...

This experiment uses a ballistic pendulum to determine the launch velocity of a metal ball. This is compared to a measurement of the launch velocity found using projectile motion. You may wish to emphasize why energy is not conserved in the initial impact of the ball into the ballistic pendulum, but momentum is, and conversely why energy is conserved as the pendulum rises but momentum is not conserved.
