  • You missed writing 4! when writing in the Taylor polynomial (P4(x)).

  • @sug15 you could but for this part of the exam you can't use a calculator so it wouldn't be possible to evaluate f(x) because we would need to know sin(1/16) and cos(1/4) right off from our heads. So we have no choice but to use the Lagrange Bound method. However I could be wrong about the calculator part I'm not american.

  • why can't you just evaluate the taylor polynomial and the function at 1/4 then find their distance apart and check if it's under 1/3000?

  • Thank you for using that board & the nice colors. Easier for me to see details.

  • Extraordinary video and I deeply appreciate you taking the time to make it. In your Sine Taylor Series at 0 (Maclaurin) video at 5:13 you say that 0 is even and that you weren't going to get into all of that, could you make a video getting into all of that? :) Wikipedia talks about it, but it does not explain it. It simply says: " Zero is an even number, because it is divisible by 2. 0 is neither positive nor negative." I find that a little confusing.
