Evaluate the improper integral

`\int_1^(\infty ) (1+tan^(-1)(x))/(1+x^(2))dx`

(Use decimal notation. Give your answer to three decimal places. Enter DNE if the integral diverges.)

`\int_1^(\infty ) (1+tan^(-1)(x))/(1+x^(2))dx=`

Evaluate the improper integral

`\int_0^(\infty ) x^(2)e^(-sx)dx(s>0)`

. (Express numbers in exact form. Use symbolic notation and fractions where needed. Enter DNE if the integral diverges.)

`\int_0^(\infty ) x^(2)e^(-sx)dx(s>0)=`
