I must find , in other words the Taylor's polynomial of order evaluated in of the function . But it says to consider the Taylor's polynomials of the functions and . I found them, so my bet would be to multiply them... but as you can imagine, I got a polynomial of degree . So my little doubt is : I only take on consideration the terms of degree and I'm done? In other words, I throw up the terms of greater degree than and I get the Taylor's polynomial of of order . Am I right?
