How to count an arcsine

How to count an arcsine

The arcsine belongs to group of the inverse trigonometrical functions. At measurement of flat corners its maximum value cannot be more than 90 ° that corresponds to a half of number of Pi if to measure a corner in radians. The lower bound of area of values corresponds -90 ° or a half of number of Pi in a negative side. The field of definitions (all this admissible arguments of function) is limited to values from-1 to +1.

Instruction

1. Use, for example, the search engine Nigma for calculation of value of an arcsine. This searcher has the built-in calculator interfaced to the converter of units of measurements. To calculate, for example, value of an arcsine from number 0.387, pass to the address http://nigma.ru and enter "(arcsin 0.387) in degrees" in the field of a search query. After sending inquiry the searcher will show result of calculation. If the same result needs to be received in radians, then units of measure do not need to be specified: "arcsin 0.387". The Google search engine has the similar calculator, but if necessary to receive value of an arcsine in degrees this operation it is necessary to make in two steps - at first to find out value in radians, then to ask Google to transfer the received number from a radian to degrees.

2. Use the program calculator which is built in the operating system if you do not trust searchers or you have no Internet access. It is the simplest to open this calculator through dialogue of start of programs - open the menu on the Start-up button, select the Execute item, enter the calc team and click the OK button.

3. Switch the interface of the calculator to "Engineering" or "Scientific" option, having opened the section "Look" in its menu and having selected the corresponding item. It needs to be made as in basic version of the interface there are no buttons for work with trigonometrical functions.

4. Enter value of an argument of function, and then choose units of measure in which the result of calculation has to be received. For this purpose it is necessary to give a mark in one of three fields (degrees, radians, are glad) under a window of input of numerical value.

5. Give a mark in a checkbox with the inscription Inv and click the button with sin tag - in standard calculations it corresponds to the sine function, but at the activated Inv installation all trigonometrical functions are replaced with the return. The calculator will calculate and will display value of an arcsine from an argument seen by you.
