All of these integrals have lower bounds of 0 and upper bounds of infinity:
Problems 1 and 2 just require me to determine whether it converges or diverges. 3 and 4 actually require a value.
1) e^(-x) * sqrt(x)
2) [tex]\frac{x*arctan(x)}{(1+x^4)^(1/3)}[/tex]
3) e^(-x) / sqrt(x)
4) x^2 * e^[-(x^2)]
I tried to use integration by parts but I went in circles
[Edit:] number 2 should have (1+x^4)^(1/3) in the denominator
