Expand the given function using Taylor's series up to two terms.
Explanation:
- given a function in 'x' than for expanding it up to two terms using Taylor's theorem for a point is given by, here, is the first derivative of the function at
- here , we have and hence we have, [tex]f(a)=f(2+2)=4+3(4)^3+(4)^4= 452 \\ f'(a)=f'(4)=1+9(4)^2+4(4)^3=401[/tex]
- putting these values in the expansion expression we get,
- hence in the expansion of the function in 'x' first two terms are ------>ANSWER
