Compute the Maclaurin series (i.e., the Taylor series about 0) of

f(x)=x^2 + arcsin(x)

up to and including terms of order two.Then: evaluate (a-zero)^2 + (a-one)^2 + (a-two)^2.

Hint:d/dx arcsin(x) = 1/sqrt(1 - x^2)

I'm getting 9/4 by just computing the Series to the second derivative and then using the rest of the formula. It's incorrect.

Also, can someone explain what the bolded part.

Thanks!
