Thank you so much. This was clear and easy to follow. I was getting frustrated with the error term because I couldn't understand what c was and what f(c) was and why they were unknowns and why we were trying to find their max value. Everything online and in my textbook said the same thing; "This is the formula for the error term and this is how we will use it; do this and do that and move that around and take this out, and bam we have a value. Easy peasy!" But it didn't make any sense to me. The small explanations you did on the side as you wrote the formula made such a difference. If they didn't give me the whole picture, they gave me the first clue ("C is a mystery value. F(c) is unknown because if we had known it we wouldn't need to calculate the error."), from which I was able to track the next couple of clues easily ("Ah, okay, so F(c) is like a mysterious quantity we add to our approximation to reach the real value of F(b), and to make it more tangible and limit the worst case scenario to a number instead of leaving it lying in an infinite interval of numbers, we attempt to get the maximum value that this unknown F(c) can take.")
It's always good to know how something came to be and why it is that way and it doesn't hurt to repeat and re-explain something that might seem obvious because more often than not, at least for me, numbers all of a sudden can become vague and obscure instead of self-explanatory. And words help dispell that.

Great video! Is there an additional video that finishes the problem? Thanks!

I just dont understand why the c is in between a and x0 (the point of our intrest) given that we're intrested in x0 then f^(n+1)(x) is supposed to be evaluated at x0 ...and other points of x are simply irrelavent . I understand that error bound should be as large as it can be by taking into account the worst case scenario and this is how we can bound it ..but x is supposed to be between a and x0 instead of c=x0 which is where we wanna know value of our approximation .
What am i missing here?

What if I was trying to estimate f(1/17)?
