Are we allowed to use functions ... like ceiling, floor, Int()?? pi*(1+i^floor(e))=0 ^ used for exponentiation Quote Link to comment Share on other sites More sharing options...

0 Guest Posted March 7, 2008 Report Share Posted March 7, 2008 1+e^(i*PI)=1+cos(PI)+i(sin(PI)) ... in trigonometric form which is equal to zero. Quote Link to comment Share on other sites More sharing options...
0 unreality Posted March 7, 2008 Report Share Posted March 7, 2008 use Euler's identity, which is the special case of Euler's formula, the equation for going around a circle with a real x axis and a nonreal y axis the special case is: epi*i + 1 = 0 which comes from this: epi*i = -1 which comes from this: etheta*i = cos(theta) + i*sin(theta) Quote Link to comment Share on other sites More sharing options...
Question
bonanova
Four basic numbers from science and mathematics have the symbols pi, e, 1 and i.
Their values are
pi = 3.1415926536 ...
e = 2.718281828459 ...
1 = unity
i = sqrt[-1]
Arrange these numbers, using them once and only once, so that they equal 0
using only the operations +, ×, and exponentiation.
Use the spoiler, Luke.
