CLDC and MIDP do not provide trigonometric functions, and there is no floating-point number in the CLDC1.0, so our choice is to check the table. Use the sin and Cos tables with 8-bit fixed-point numbers. The following is the code in the WTK demo, which provides only a limited number of angles, which are used to refine the angle value as needed. Sines of Angles 0, a, a, m, a, all *256 private static final in

1. How to write COS60 in unity)Deg2rad converts a 60 angle to radians, because the inside parameter can only be filled with radians2. Calculates a vector that is obtained after a Vector3 rotates the specified angle around the center of rotation/// ///calculates a vector that is obtained after a Vector3 rotates the specified angle around the center of rotation. /// /// source Vector3 before rotation/// Rotary Axis/// Rotation Angle/// new Vector3 to be obtained after rotation PublicVector3 V3rota

This article mainly introduces the use of the Cos () method in Python to compute trigonometric functions, which is the basic knowledge of the introduction of Python, the need of friends can refer to the The Cos () method returns the cosine of x radians. Grammar The following is the syntax for the Cos () method: COS (x) Note: This function is not directly accessible, so we need to import the math module
