  4. The sine value will be displayed in the result field.

Understanding the Sine Function

The sine function is a fundamental trigonometric function that takes an angle as input and returns a value between -1 and 1. In a right triangle, the sine of an angle is the ratio of the length of the side opposite the angle to the length of the hypotenuse.

Conversion Between Degrees and Radians

By default, the calculator uses degrees as the angle unit. If your angle is in radians, make sure to select the "Radians" option. To convert degrees to radians, multiply the angle by π/180. To convert radians to degrees, multiply the angle by 180/π.

Applications of the Sine Function

The sine function has numerous applications in various fields:

  • Physics: Wave motion, oscillations, and harmonic motion
  • Engineering: Structural analysis, signal processing, and electrical engineering
  • Navigation: GPS and surveying
  • Computer graphics: 3D modeling and animation
