This study was conducted to give a trigonometric representation, using complex numbers and plane, of the increase in dry matter indigestibility [IDMI] with growth of forages. The following results were obtained. Divisional calculations between two coordinates of dry matter indigestibility [DMI] expressed using complex numbers were related to the subtraction theorem of tangent. This relation might give some information on DMI changes, namely IDMI, the geometric mean of DMI [GMDMI] and relative IDMI (=IDMI/GMDMI). Changes in dry weight and indigestible dry weight with forage growth were visualized by the geometric representation. Therefore, there were four information on IDMI given by the trigonometric representation of DMI on the complex plane. It was suggested that the complex representation of DMI of forages derived, from the subtraction theorem of tangent, some information on IDMI with forage growth.
