How do I evaluate this integral?<img src="https://tex.z-dn.net/?f=%20%5Cint%5Climits%20%7B%20%5Cfrac%7Bx%7D%7Bx%5E4%2B1%7D%20%7D

One thing you could try is to set $x=\sqrt y$ . This makes $y=x^2$ , so that $\mathrm dy=2x\,\mathrm dx$ , and $y^2=x^4$ . So the integral is

$\displaystyle\int\frac x{x^4+1}\,\mathrm dx=\frac12\int\frac{\mathrm dy}{y^2+1}=\frac12\arctan y+C=\frac12\arctan(x^2)+C$

A "trickier" way to do it is to write

$x^4+1=(x^2+\sqrt2x+1)(x^2-\sqrt2x+1)$

so you could decompose the integrand into partial fractions. But that's more work than needed.

A Country Has A Goal To Build 12,000 bus stop shelters in 48 months. If the country builds 215 bus shelters each month, will it

No because if you do the math if you do 215 x 48 in doesn't reach to 12000 at all.
