WebOne of the most fundamental equations used in complex theory is Euler's formula, which relates the exponent of an imaginary number, e^ {i\theta}, eiθ, to the two parametric equations we saw above for the unit circle in the complex plane: x = cos θ. x = \cos \theta x = cosθ. y = sin θ. y = \sin \theta. y = sinθ.

But some utilities, like Three Gorges Corporation in west-central China, are ... WebPerhaps that is why Euler's formula works! And when you look into it actually does explain why it works because since both the derivatives of trig functions and powers of i have a "cycle" of 4, only the powers of x and the factorials don't cycle, which is exactly like the Maclaurin expansion of trig functions so you can factor out the cos(x) and i*sin(x) to get …
