Trigonometric functions and JavaScript

1. Trigonometric Functions

• sin& (ratio of edge to hypotenuse) cos& (ratio of adjacent edge to hypotenuse) tan& (ratio of edge to adjacent edge)

The use of 2.JavaScript functions

• Math.sin ()
• Math.Cos ()
• Math.tan ()

3. Angle

• The relationship between angle and radian
  • 1 radians equals the radius of R
  • 360=2π
  • 1 degrees of the radian of the JS notation 1*math.pi/180
  • To find the length of the Edge is Math.sin (math.pii/180) *r;
  • The length of the adjacent Edge is Math.Cos (math.pi/180) *r;
  • The length of the adjacent Edge is Math.tan (math.pi/180) *r;

4. Examples of circular motions
