Find a power series representation for the function. (Give your power series representation centered at x = 0.)f(x) = x3x2 + 1f(

makkiz [27]

I suppose you mean

$f(x)=\dfrac{x^3}{x^2+1}$

Recall that for $|x|$ , we have

$\dfrac1{1-x}=\displaystyle\sum_{n=0}^\infty x^n$

Then

$\dfrac1{1+x^2}=\dfrac1{1-(-x^2)}=\displaystyle\sum_{n=0}^\infty(-x^2)^n=\sum_{n=0}^\infty(-1)^nx^{2n}$

which is valid for $|-x^2|=|x|^2$ , or more simply $|x|$ .

Finally,

$f(x)=\displaystyle\frac{x^3}{x^2+1}=\sum_{n=0}^\infty(-1)^nx^{2n+3}$

Integral of (x^2)/(e^x^3)

Lesechka [4]

$I=\displaystyle\int\frac{x^2}{e^{x^3}}\,\mathrm dx$

Substitute $y=x^3$ and $\mathrm dy=3x^2\,\mathrm dx$ . Then

$I=\displaystyle\frac13\int\frac{\mathrm dy}{e^y}=-\frac1{3e^y}+C=-\frac1{3e^{x^3}}+C$

Is 540171 divisible by 9?

Iteru [2.4K]

Image is attached below.

If the sum of the digits its divisible by 9,

then the original number is divisible by 9.

Since 18 (the sum of the digits) is divisible by 9,

the number 540,171 is also divisible by 9.
