Hi,

I'm not sure how to present an answer to this kind of question. It states:

Present the 3rd-Degree Taylor Polynomial $\displaystyle P_{a,2}(h)$ as well as the Lagrange remainder for the function $\displaystyle f(x,y) = x^3y + sin(xy)$.

Then let $\displaystyle a = (1, \pi)$ and write this polynomial in matrix form.

Thanks a lot!
