After converting a surface over the region that \rho=sin\phicos\theta/a + sin\phisin\theta/b + cos\phi/c
I also have that this region is equal to 1.
I can't seem to get anywhere..
Let C be the curve obtained by intersecting the sphere x^2 + y^2 + z^2 = a^2 with the surface root(x^2 + y^2)cosh(arctan(y/x))=a.
Find the length in the first octant that joins the points A (a,0,0) and B(x,y,z).
Im not sure what to do. Should i change it into different types of coordinates?
