Proof of e^(ix) = cos(x) + i*sin(x)

Proof of e^(ix) = cos(x) + i*sin(x)

Let's say we're searching for a function y that is y' = k*y. It turns out we have that function which is
y = e(kx) for which y' = k*(ekx)

How about k = i
y' = i*y (1)

What if the pain we face lead us to something bigger than our imagination?


                Actually, the idea of future doesn’t exist. I mean, there are now and past. Every action we’ve done is literally past.
