Tangent - one of trigonometrical functions most often designated by the letters tg though also the designations tan meet. It is the simplest to present a tangent as the relation of a sine of the angle to its cosine. It is odd periodic and not continuous function which each cycle is equal to Pi's number, and the point of a gap corresponds to a mark in a half of this number.
It is required to you
- Internet access or Windows OS.
Instruction
1. In the presence of Internet access use online services which place calculators of trigonometrical functions on the pages. For example, pass to the http://planetcalc.ru/307/ page and in the field "Corner" enter the size of a corner which tangent is required to be defined. If this value is given not in degrees, and in radians, grads, angular minutes or seconds, give a mark in the respective field. Then press the orange Calculate button, and scripts of service will make necessary calculations. The answer read in the field "Value" of the line "Tangent" from the table placed below the orange button of sending data. Except a tangent in this table it is possible to see values of ten more trigonometrical functions corresponding to the entered corner.
2. If there is no Internet access, it is possible to use the program calculator which is a part of the Windows operating system. For its start press the Win key, enter couple of letters of the name of the program - - and press Enter. The internal search engine will find and will start the necessary application. In the versions released earlier than such search engine was built in the OS main menu (for example, Windows XP), use for start the Implement clause in the same menu - enter into a window of dialogue of calc and click the OK button.
3. Switch the interface from the Usual mode to "Engineering" - press "hot keys" Alt + 2 or select item with the name of this mode in the section "Look" of the menu of the calculator.
4. Gain the size of a corner which tangent is required to be defined. By default the calculator considers the entered value a-degree measure, but if it is given you in radians or grads, give the corresponding mark under the main window of the calculator. Then press the button marked with the inscription tan, and the program will calculate and will display result to within 32 signs after a comma. It can be copied simple pressing of the keys Ctrl + C that then to use at discretion.
