Euler's identity is the following equation: \(e^{i\pi} + 1 =0\) where \(e\) is the exponential number and the base of the natural logarithm, \(\pi\) is the ratio of the circumference and the diameter of any circle and \(i\) is the imaginary unit that satisfies \(i^2=-1\). If you want to know where it comes from (its derivation), you need to learn about advanced trigonometry and complex numbers.But if you know about the Taylor Expansion of sine, cosine and e, you can take a look at this website. Even if you don't know about the Taylor expansions, check the site out!(simply because it's cool!). Mursalin Habib · 4 years, 2 months ago

A generalized form is http://www.proofwiki.org/wiki/Euler's_Formula. We need to put θ=π in the identity Lab Bhattacharjee · 4 years, 2 months ago
