SUMMARY

The discussion centers on the confusion surrounding the definition of the "tenth Taylor polynomial" for the function sin(x). Participants clarify that the term refers to the polynomial constructed using derivatives up to the tenth order, which may include a remainder term that can lead to a degree of x^11. The Taylor polynomial formula is essential for understanding this concept, as it dictates the structure of the polynomial and the inclusion of higher-order terms. The ambiguity arises from the interpretation of what constitutes the "tenth" polynomial, highlighting the need for precise definitions in mathematical problems.

Homework Statement



So, we are supposed to find the tenth taylor polynomial of sinx. On wolfram, I get a final term with x^11 at the end. How does that make sense?! According to the formula, n=10 so the maximum degree should be 10...

Homework Equations



Taylor polynomial formula.

The Attempt at a Solution



I would stick with what the formula tells me, but my homework wants me to write x^11. I DEMAND TO KNOW WHY AS ANY MATHEMATICIAN/SCIENTIST :) I am in grade 11.

It would be best to start by defining "10th Taylor polynomial". Is this a polynomial with exactly 10 terms? 9 terms plus a remainder counting as the 10th? A polynomial which uses up to and including the 10th derivative (not the same as the above)? With or without remainder?

Your problem is a semantic one, not a mathematical one.

For all I know, you are in grade 22.

The question isn't very well posed as you have stated it. What does "tenth Taylor polynomial" mean? Ten terms? Ten non-zero terms? Up to ##n=10##? And even that would depend whether the index in the summation gives consecutive integers or just odd ones. Does it include the remainder? So an exact statement of the problem would be helpful.
