The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. WebAddition and Subtraction Formulas for Sine and Cosine. In a right triangle with legs a and b and hypotenuse c, and angle α opposite side a, the trigonometric functions sine and cosine are defined as. sinα = a/c, cosα = b/c. This definition only covers the case of acute positive angles α: 0<90°.
