well the limits are Z=0, z=5, x=0, x=4, but what I'm after is what type of integration to use i.e. by substitution, parts, product malarchy or what? Just from looking at the bit \left(\frac{xz}{\sqrt{16-x^{2}}}+x\right) as I havn't the foggiest.
Thank you.
Why hello,
I have come across the surface integral \int\int(\frac{xz}{\sqrt{16-x^{2}}+x})dzdx
My query is, which type of integration do I use to solve the first part of this double integral. The solution is: \int(4x+8)dz = 90
I learned all the hard (at my level) bits like grad, div, curl and now I'm falling at the first hurdle on the exam papers:
The question is: Express the circle of radius 3, centred at (1,0,3) and lying in the (x,z) plane in the form of r(t) = x(t)i + y(t)j + z(t)k
I was hoping there was...
