EULER’S FORMULA FOR COMPLEX EXPONENTIALS

math.gmu.edu

EULER’S FORMULA FOR COMPLEX EXPONENTIALS According to Euler, we should regard the complex exponential eit as related to the trigonometric functions cos(t) and sin(t) via the following inspired deﬁnition:eit = cos t+i sin t where as usual in complex numbers i2 = ¡1: (1) The justiﬁcation of this notation is based on the formal derivative of both sides,
