A trigonometric identity that expresses the subtraction of cosine of double angle from one as the two times square of sine of angle is called the one minus cosine double angle identity. The subtraction of cosine of double angle from one is mathematically equal to the two times the sine squared of angle. It can be written in mathematical form as follows. It is used to simplify the one minus cos of double angle as two times the square of sine of angle. It is used to expand the two times the sin squared of angle as the one minus cosine of double angle. The angle in the one minus cos double angle trigonometric identity can be denoted by any symbol. Hence, it also is popularly written in two distinct forms. In this way, the one minus cosine of double angle formula can be expressed in terms of any symbol.
