Question
Let me know if my thinking process and computations are correct and if not let me know why please
The principal part of f(x)=x+x²-√₂²+x" for x->0+ (with respect to up(x) = x) is:
a) x + x³
b)x³
e)-4/3
d) a
how I solved it, Let me know if it's correct, if not let
me know why
2+x²³ - (x³ +2²)¹³ »n+x²-x[|+ __ x)
⇒n+2³_n-12²
⇒2³-1/²
23.
so we choose the
one with the smallest
degree
So C.
