How do I evaluate: http://www.wolframalpha.com/input/?i=integral+sqrt((x^2+%2B+1)^2%2F(x^2+-+1)^2)%2C+from+0+to+1%2F2 ?
Any help would be greatly appreciated!
Thanks in advance!
You cannot do that! Partial fraction decomposition cannot be used on this fraction because the degree of the numerator is not less than the degree of the denominator.
Notice how you got
when you did the work. But now, let's check the answer:
But this doesn't equal the original fraction.
