Measures of angle |

You can change measure of agle for some trygonometric functions (Sin, Cos, Tan,
...).

Example

To calculate **Sin(Pi)** where **Pi** is angle, you must choose **rad** button (pic.).

Unit of plain angle.

Round angle = 2*Pi = about 6,28 rad; where Pi~3,1415...

Unit of plain angle.

Round angle = 360 degrees

Unit of plain angle.

1 grad = 1/100 right angle

Round angle = 400 grad

Unit uses in geodesy.

Round angle = 2*Pi rad = 360 deg = 400 grad

1 rad = 180/Pi (about 57,3) deg = about 63,661977 grad

1 deg = Pi/180 (about 0,0175) rad = 1,(1) grad

1 grad = Pi/200 (about 0,0157) rad = 0,9 deg.
