Let $\displaystyle g(x)=\frac{1}{\sqrt{x}-1}.$

(a) Use a calculator or computer algebra system to evaluate $\displaystyle \int_{2}^{\,t} {g(x)}\, dx$ for $t$ = 5, 10, 100, 1000, and 10000. Make sure each answer is correct to three decimal places.

$t$ = 5:

$t$ = 10:

$t$ = 100:

$t$ = 1000:

$t$ = 10000:

(b) Use the Comparison Theorem to determine whether $\displaystyle \int_{2}^{\,\infty} {g(x)}\, dx$ is convergent or divergent.
