Angle and radian Conversion

In Python and Delphi, angle calculation is involved, such as sin (X) and cos (x). Here, X is a radian rather than a direct angle.

Therefore, when calculating the trigonometric function of the corresponding angle, you need to convert the angle to radians before calculation.

 

The conversion formula for radians and degrees is:

Angle = radian * 180.0f/PI

Radian = angle * PI/180.0f

 

For example, to calculate the 90-degree sine value, you should write it in Python:

1 Math. Sin ( 90 * Math. Pi / 180.0 )
