It is defined as the values of all the trigonometric function based on the value of the ratio of sides in a right-angled triangle. The ratios of sides of a right-angled triangle with respect to any of its acute angles are known as the trigonometric ratios of that particular angle.

 

  • sine: Sine of an angle is defined as the ratio of the side opposite(perpendicular side) to that angle to the hypotenuse.
  • cosine: Cosine of an angle is defined as the ratio of the side adjacent to that angle to the hypotenuse.
  • tangent: Tangent of an angle is defined as the ratio of the side opposite to that angle to the side adjacent to that angle.
  • cosecant: Cosecant is a multiplicative inverse of sine.
  • secant: Secant is a multiplicative inverse of cosine.
  • cotangent: Cotangent is the multiplicative inverse of the tangent.
