Question

evalu(ate the integral sqrt(4+x^2)/(X^4)dx from 0 to 1

Answer 1

if we rationalize the numerator .. maybe that will get it into a more familiar form

Answer 2

nah, that dint work out nicely

Answer 3

let u = 4+x^2, x^2 = u-4; 2x dx = 1 du

sqrt(u) du
------ --------
(u-4)^2 2sqrt(u-4)

hmm

Answer 4

exact or approximate?
