I really appreciate the advice! The last time I computed double integrals was in Calc 3 a couple years ago. I now see that using integrals in practice is slightly different than when computing them in a class. I understand the basic concepts, but am rusty on the details. Thanks a lot!

One question I have for you though...How did you come up with the 11.8%? I'm also curious where f(theta) = sin(theta) comes from in this formula? Thanks for your input.

Ok...I think I see how to handle this. What I did was computed the dbl integral above symbolically to get, \int _ {\phi = 0}^{2\pi}d\phi \int _ {\theta = 0}^{\pi}sin \theta d\theta = -(phi-2*pi)*(cos(theta)+1) = 4\pi Now I can describe phi and theta in terms of the offset distance...

Thank you for your response. Percentage = 100_cm^2/(11.9_cm^2) = 8.40 = 840% On the other hand, if I flip the ratio, Percentage = 11.9_cm^2/100_cm^2 = 11.9% I thought of trying this yesterday; however, I figured this was too good to be true. Shouldn't the percentage be...

We have a surface that is 10 cm x 10 cm. That surface is uniformly covered with a radioactive material. When radioactive material decays, it has a equal probability of emitting radioactive particles, in this case beta particles, in any direction (360 degrees). We have a detector that...

Thanks for your input... Violin Acoustics What if as a result of using modern day experimental test instrumentation, we were able to find a way to get the same sound quality (or “timbre”) as is obtained from aged instruments? What if we were able to get this same sound quality (or better)...

Hello All, My partner and I are mechanical engineering technology students who are in search of a feasible senior design project related to acoustics. During the first semester we will be doing the theoretical parts then during the second semester we will be doing the hands-on...
