dx / sqrt (x^4 + 4x^3) from upper limit b=infinte and a=1
1 + 2t(cos(t))^2(dt)/ (t)^3 from upper limit infinte an a=lowerlimit=pi
Please I need help using the comparison method to determine if integral converges or diverges.!
so (cost)^2 <=1
am still not quite understanding it, can you give me a hint on how to begin i know i have to find a function that I know is either convergent or divergent 1/t^3 would be my function? am so lost? i wana know how to start if u may.
And for the first question I would like to knnow what hapened to the sqrt( of the function ) the radical u showed me disspeard?
