Ok, I think I've got it... Wow. This is so much more complicated than any other expression. Wow.

That doesn't seem to work. I end up with imaginaries in the expression, unless I am doing something wrong.

Thanks dextercioby. If I understand your hint, I would factor (t^2+4)^2-8t^2 into two factors, use partial fractions, and then integrate the two expressions that would result?

Homework Statement \int\frac{1}{t^4+16}\,dt Homework Equations Various integration formulas. I am pretty stuck.The Attempt at a Solution I have tried various substitutions, with no success. I tried t^2 = 4u, hoping to get it into the form 1/(u^2+1) so I could use the arctan formula, but then...

Thank you both, VERY much. Hage567, yes, I was calculating the completely wrong thing, thank you. I think I still must be doing something wrong, since I get answers that are very different, or I don't understand why they should be this different. I'm also wondering why using the mean-value...

Wow, nobody? Well, I fixed a couple of typos, but I am no closer to certainty. If I've violated some rule, I'm sorry. I'm new here :-) But I would really appreciate some help. Thanks, Brett

Homework Statement I have attached a diagram. In case you can't view it, it shows an infinitely long wire I_i = 5.00 A on the positive y direction. 0.100 m to the right, there is a rectangular loop of dimensions 0.150 m x 0.450 m, the long side is parallel to the infinitely long wire to its...
