Combine the Taylor Series expansion of the Cosine and Sine functions and take the absolute value of its sum. Which function does this Taylor Series expansion resemble? This blew my mind the first time I saw it.

I did this problem this semester, actually. I did it a different way, though. I substituted "i Θ" in for "x" in the Taylor series for e^x and ended up with Euler's formula. e^(iΘ) = cos(Θ) + isin(Θ)

At least I think that is where you're going.

or a differential depending on your lingeaux

Yea, I guess it depends on what application you use all this stuff for. I've heard some terms and didn't know what they were and it turned out they were just used for business calc.

Anyway, gotta get back to studying. . . peace.
