Euler's identity - Wikipedia
In mathematics, Euler's identity[note 1] (also known as Euler's equation) is the equality where. is pi, the ratio of the circumference of a circle to its diameter. Euler's identity is named after the Swiss mathematician Leonhard Euler. It is a special case of Euler's formula when evaluated for .

How does $e^{\\pi i}$ equal $-1$ - Mathematics Stack Exchange
$e^{\pi i}$ corresponds to $z = (-1, 0) = -1$ on the unit circle in the complex plane. That is, it is positioned $\pi = 180^\circ$ from the position (1, 0) on the complex unit circle. It has no "height" in the direction of either $i$ or $-i$. From $e^{\pi i} = -1$, we obtain Euler's Identity: $e^{\pi i} …
Prove that $e^{i\\pi} = -1$ - Mathematics Stack Exchange
Oct 13, 2021 · $e$=$\lim\limits_{n \to \infty}(1+\frac{1}{n})^n$ we arrive at Euler's identity. The $\pi$ itself is defined as the total angle which connects $1$ to $-1$ along the arch.

eiπ = cos π + i sin π. eiπ = −1 + i × 0 (because cos π = −1 and sin π = 0)
Question Corner -- Why is e^(pi*i) = -1? - University of Toronto ...
Jan 29, 1997 · First of all, when x=0, sin x equals zero but increases as x increases; in fact, the slope of the graph of y = sin x at the point (0,0) is 1, which is another way of saying that the rate of increase there is 1, so f'(0) = 1.
Euler's formula: e^(i pi) = -1 - University of Waterloo
Euler's formula: e^(i pi) = -1 The definition and domain of exponentiation has been changed several times. The original operation x^y was only defined when y was a positive integer.
Q: Why is e to the i pi equal to -1? - Ask a Mathematician / Ask a ...
Oct 29, 2009 · The reason why this works is the repeating sequence of (non-negative integer) powers of `i`: `1, i, -1, -i, …` which has has two properties of interest: It alternates 1 complex value and 1 non-complex value, and it alternates 2 positive values and 2 negative values.
Intuitive Understanding Of Euler’s Formula – BetterExplained
Therefore, $e^{i \pi}$ means starting at 1 and rotating pi (halfway around a circle) to get to -1; That's the high-level view, let's dive into the details. By the way, if someone tries to impress you with $e^{i \pi} = -1$, ask them about i to the i-th power. If they can't think it through, Euler's formula is still a magic spell to them.
