Next we investigate the values of the exponential function with complex arguments. This will leaf to the well-known Euler formula for complex numbers. that the idea of multiplying something by itself an imaginary number of times does not seem to make any sense. To understand the meaning of the left-hand side of Euler’s formula, it is best to recall that for real numbers x, one can instead write ex= exp(x) and think of this as a function of x, the exponential function, with name \exp". 2019-08-20 · Euler Formula and Euler Identity interactive graph. Below is an interactive graph that allows you to explore the concepts behind Euler's famous - and extraordinary - formula: e iθ = cos(θ) + i sin(θ) When we set θ = π, we get the classic Euler's Identity: e iπ + 1 = 0. Euler's Formula is used in many scientific and engineering fields.

Similarly, , so that and for any imaginary number , , where is real. Finally, from the polar representation for complex numbers, where and are An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i2 = −1. The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25. By definition, zero is considered to be both real and imaginary.

He used i, an "imaginary number" to allow him to create a relationship between two quantities that one would normally not guess to be related to each other. The Euler’s form of a complex number is important enough to deserve a separate section. It is an extremely convenient representation that leads to simplifications in a lot of calculations. Euler’s representation tells us that we can write cosθ+isinθ as eiθ cos θ + i sin
Euler’s Identity stems naturally from interactions of complex numbers which are numbers composed of two pieces: a real number and an imaginary number; an example is 4+3i. Imaginary numbers are something of another nature. At their birth, imaginary numbers were conceived as a mathematical tool for being able to operate with squared roots of negative numbers, and the
So, Euler's formula is saying "exponential, imaginary growth traces out a circle". And this path is the same as moving in a circle using sine and cosine in the imaginary plane.
