If it's hard to find an inequality for you may try the following:
Put and the integral becomes which is clearly divergent.
dx / sqrt (x^4 + 4x^3) from upper limit b=1 and a=0
Does this integral converge or diverge from the work i did am thinking that it divergers, help someone confirom or show me how it worked!!
I poseted a simliar thread before same question but with different limits of integration, any help would be appreciated.
