euler identity造句

So if the equation above were defined, it would not be original research, it would just be a rearrangement of eulers identity.
Combining, for instance, Taylor series and the Euler identity, you could prove e ix = isin ( x ) + cos ( x ).
As to Euler identity, if you understand geometrically the complex multiplication, you can easily prove that the length ( = classical total variation ) of the curve exp ( ix ) on the interval [ 0, t ] is exactly t .-- talk ) 06 : 45, 2 June 2009 ( UTC)
