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:

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 ...

The first formula to calculate the area of a triangle is area A = (1/2) * a * b * Sin(C), where a and b are the lengths of the two sides of the triangle and C is the value of the angle of the triangle that lies in between the two sides a, b. Now substitute these values in the given formula to find the area if you have...
