I've been doing intergrals, volumes, and areas all morning. But this is one has got me stumped. Any help??

A. Find the number a such that the line x=a bisects the area under the curve y=1/(x^2), 1<=x<=4.

B. Find the number b such that the line y=b bisects the area in part (a).

Thanks in advance

John

I would do a lot worse in school if I didn't have help from everyone here!!!!!
