### Taylor / Maclaurin Series Expansion - Proof of the Formula

Taylor / Maclaurin Series Expansion - Deriving the Formula. In this video, I show how to find the Taylor series expansion for a function, assuming that one exists! It is nothing too heavy: we just take derivatives and plug in the value at which we are centering the function. I do not find any Taylor series of specific functions in this video, nor do I justify when a Taylor series expansion is valid (not all functions have power series expansion!).
