Prove that $e^{i\\pi} = -1$ - Mathematics Stack Exchange When I first found out that eiπ = −1 e i π = 1, I was blown away Does anyone here know one of (many I'm sure) proofs of this phenomenal equation? I can perform all of the algebra to get the −1 1 But, where does this come from? What is the derivation?
e. i. or e. g. ? | UsingEnglish. com ESL Forum First, it's not "e i" it's "i e " Both "i e " and "e g " are from Latin and have different meanings and uses: i e = "id est" which means approximately "that is [to say]" Use it to expand further on a term or statement: The countries of North America, i e , Canada, the US and Mexico e g = "exempli gratia" which means approximately "for [the sake of] example" Use it to introduce an example or
How Do I Understand $e^i$, the Euler Form of Complex Number Raising something to an imaginary number is weird, I have a hard time wrapping my head around that And e e seems even more common and comes up in many situations, such as: the non-geometric definition of sin, the fourier transform, eπi = −1 e π i = 1 !?! (see, for instance, here) I'd really like to have some light shed on the matter How do I begin to form an intuitive grasp of ei e i ?

How would you explain why - Mathematics Stack Exchange Hi I was asked by a friends child who is in middle school why eiπ + 1 = 0 e i π + 1 = 0 Now I couldn't think of a way to explain it so he would understand Albert Einstein once said “If you can't explain it simply, you don't understand it well enough” so how would I explain it
How to prove Eulers formula: $e^{it}=\\cos t +i\\sin t$? Actually, it is common to define eit e i t using your equation If something is to be proved we must start by asking what we know about the involved parameters, so how is your definition of eit e i t? Do you use a series or some other limit process?
