How do you verify euler's formula? - Answers

Euler's formula refers to a formula in complex analysis that links trigonometric function with the complex exponential function. It states that, for any real number x,eix = cos(x) + i*sin(x) wherei is the imaginary square root of -1, and the angle x is measured in radians.That formula is not easy to verify.However, it is quite possible that what the questioner calls the Euler formula is actually a reference to the Euler characteristic. In its basic form, it states that for any convex polyhedron, the numbers of vertices (V), edges (E) and faces (F) are related byV - E + F = 2Verification in the case of basic polyhedra is simple but general verification is not simple.
