This video shows you how to convert temperatures from Fahrenheit(F) to Celsius(C). In the video, the example of 75 degrees F is used. The formula for converting Fahrenheit to Celsius is given by temperature in Celsius= (temperature in Fahrenheit- 32)/1.8. So for 75 degrees F we take 75 in place of temperature in Fahrenheit. Therefore the equation becomes (75-32)/1.8=C . Further 43/1.8=c and finally C= 24. Hence 75 degrees Fahrenheit= 24 degrees Celsius . This conversion is used as Celsius is ...

This video teaches how to calculate the acceleration of a car. The information for this calculation is for a car that accelerates by 12 meters per second in a time of 3 seconds. So to calculate acceleration use the following formula: acceleration equals change of speed divided by time. So, using the information provided for this calculation, acceleration equals 12 meters per second divided by a time of 3 seconds. So this gives an acceleration of 4 meters per second squared.
This video shows you how to get the quadratic equation for the quadratic function with roots; (5,0), (12,0) which passes through the point(8,6). It shows a man solving this problem using a black board and chalk to clearly demonstrate the method of plugging in the respective coordinates to arrive at an answer. After watching this video, any person over the age of twelve will know how to use quadratic functions to derive quadratic equations and solve mathematical problems with this particular m...
In this tutorial the author shows how to find out the volume of a cube. The author shows first to mark the length of the cube and substitute it in the formula for volume of the cube which is s*s*s, where s is the length of the cube. Therefore the volume of a cube is nothing but the length of the cube multiplied to it self three times. By following the method given in this tutorial you can easily compute the volume of a cube with a given length.
Calculating The Area Of A Parallelogram A parallelogram is a 4-sided shape formed by two pairs of parallel lines. Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is:

In this tutorial the instructor shows how to derive a straight line equation. He shows us a process that consists of two steps. In step one he uses the slope formula to obtain the slope of the line which is the ratio of difference of y-coordinates and difference of x-coordinates. Now in the step two he uses the slope he obtained in the first step and equates it two a another slope derivation which uses a generic x, y variables and a real point. Now solving this equation he arrives at the equa...
In this video the instructor shows how to calculate the area of a circle using squares. She starts with the formula of the circumference which she says is circumference C = Pi * D, where D is the diameter of the circle. Now she says that you can turn the shape of circle into a square and compute the area of the square there by calculating the area of the original circle. She shows how to do this by cutting up the square into sectors and arranging them in the form of a rough square and calcula...

The formula for finding the volume of a cone is (1/3) pi x radius^2 x height. You can find the radius of your cone by finding half the length across the center of the circle which is the cone's base. After plugging in all the values into this equation, you will be able to find the volume of any cone when given...
The video is a tutorial in trigonometry. The teacher teaches that the tangent or the tan of an angle is the ratio of the opposite side to the adjacent side of a right angled triangle. If one side and one angle is given then the value of the unknown side can be found by solving the equation tan of angle is equal to opposite upon adjacent side. If the angle is to be found then the tan inverse of the value is seen in the calculator.
The video describes the "Calculation of the surface area of the cone without a slant". If the base circle diameter (d) and the height of the cone (h) are known, then the following procedure can be used for finding out the surface area oh the cone:

The Manhattan is one of America's classics. It originally was based with rye but now predominately uses bourbon as the base. Rye is quite a bit more dry and there are a lot more smokey woody tones in it where as bourbon is slightly sweeter and carries vanilla tones. The vermouth used in this recipe was Ponti Rosso. It has some spicy notes that complement the sweeter flavors very well. If you want to use a really good vermouth, use Carpano Antica Formula. Any high quality bourbon such as Maker...

Christmas is just a few weeks away and the decorating has already begun. The centerpiece for most home during the holiday is, of course, the Christmas tree. But let's face it—that tree can be a big pain in the ass to decorate. You'll run out of tinsel, your lights will be too short, and a missing bulb with throw the whole thing off balance.
In our previous article, we learned how to take advantage of a feature, Dynamic Data Exchange (DDE), to run malicious code when an MS Word document is opened. Because Microsoft built DDE into all of its Office products as a way to transfer data one time or continuously between applications, we can do the same thing in Excel to create a spreadsheet that runs malicious code when opened. The best part is, it will do so without requiring macros to be enabled.
In this video, we learn how to use Visual Basic to convert temperature units. To start, make two command buttons. After you have created these, make sure you label them. The first command button should say "celsius to fahrenheit" and the second should say "fahrenheit to celcius". After this, make one text box and one label box. Now you will convert celsius to fahrenheit using the formula "F=(9/5*C) + 32". and you will be able to use this to convert temperature units. Save this and use it for ...

When we are building programs that communicate over a network, how can we keep our data private? The last thing we want is some other lousy hacker sniffing our packets, so how do we stop them? The easy answer: encryption. However, this is a very wide-ranging answer. Today we're going to look specifically at how to encrypt data in Python with dynamically generated encryption keys using what is known as the Diffie-Hellman key exchange.
How much you've actually spent and how much you think you've spent are usually two completely different results, and is especially true on Amazon when it's so easy to click and buy. You might think you've given Amazon a couple thousand over your lifetime, when the fact is that it's three or four times that amount.
