By rule and regulation, we are allow to do only one excercise at a time..so i do only 1st one..
Any doubt in solution then comment below....
for both values of y , we see
that series for n=2 gives less error as compared to series n=1
.....
And for n=0 , there is no term in series...because series start for n=1 ...

5. A function f has Taylor series (at 0) f(x)=0+2x+ 4x2/2! + 3x3/3!+... Assume f−1 exists. Find as much of the Taylor series of f−1 (at 0) as you can. (Since you only know the first few terms of the Taylor series for f, you can only figure out f−1. (Hint: There are two ways of doing this problem. One is get the derivatives of f−1 from knowing the derivatives of f; we talked about the first derivative in January...
