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.

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.

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...
