Euler’s Formula Page 1 of 4 Euler’s Formula (For Your Enjoyment{Will Not Be On Tests) Using Taylor series we can get an amazing result, known as Euler’s formula, which relates exponential functions, sines and cosines. First, we need to introduce the complex number i, which is de ned by i2 = 1. This means we can write things like p 4 = p 4 ...

Euler’s formula then comes about by extending the power series for the expo-nential function to the case of x= i to get exp(i ) = 1 + i 2 2! i 3 3! + 4 4! + and seeing that this is identical to the power series for cos + isin . 6. 4 Applications of Euler’s formula 4.1 Trigonometric identities

Euler’s Formula Theorem (Euler’s Formula) The number of vertices V; faces F; and edges E in a convex 3-dimensional polyhedron, satisfy V +F E = 2: This simple and beautiful result has led to deep work in topology, algebraic topology and theory of surfaces in the 19th and 20th centuries.

4 Applications of Euler’s formula 4.1 Trigonometric identities Euler’s formula allows one to derive the non-trivial trigonometric identities quite simply from the properties of the exponential. For example, the addition for-mulas can be found as follows: cos( 1 + 2) =Re(ei( 1+ 2)) =Re(ei 1ei 2) =Re((cos 1 + isin 1)(cos 2 + isin 2)) =cos 1 ...

Euler’s Formula: The purpose of these notes is to explain Euler’s famous formula eiθ = cos(θ)+isin(θ). (1) 1 Powers ofe: FirstPass Euler’s equation is complicated because it involves raising a number to an imaginary power. Let’s build up to this slowly. Integer Powers: It’s pretty clear that e2 = e × e and e3 = e × e × e, and so on.

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,

with Euler’s formula ei = cos + isin . One can convert a complex number from one form to the other by using the Euler’s formula: z= x+ iy , z= ˆei ; where x= ˆcos ; y= ˆsin ; ˆ= p x2 + y2; = tan 1 y x; where we often restrict 0 2ˇor ˇ ˇ. Otherwise, the conversion from Cartesian to polar coordinates is not unique, can
