WebThe cofunction identities for sine and cosine state that the cosine of an angle equals the sine of its complement and the sine of an angle equals the cosine of its complement. The hypotenuse in the above figure is of unit length so that the sine of an angle is the length of the opposite side and the cosine of an angle is the length of the side adjacent to it.; WebWhat is Sine in Mathematics? Sine, is a trigonometric function of an angle. The sine of an angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to (which divided by) the length of the longest side of the triangle (thatis called the hypotenuse).
