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.(adsbygoogle = window.adsbygoogle || []).push({});

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?
