I don't really understand how to derive taylor polymomials for questions like these for example
find the 3rd degree taylor polymomial about the origin of
f(x,y) = (cos y) ln(xy+1)
can someone please help and explain what the starting steps are
yes. Do I just substitute the terms of the question into the taylor series of cos x and ln 1+x?
I was looking over some examples and that is what my instructor did. But what about a question like
cos(xy)/[1 + y^2]
there isn't a standard representation for the denominator.
