Gfind the area of the surface over the given region. use a computer algebra system to verify your results. the sphere r(u, v) = a sin u cos v i + a sin u sin v j + a cos u k, where 0 ≤ u ≤ π and 0 ≤ v ≤ 2π

Presumably you should be doing this using calculus methods, namely computing the surface integral along .

But since describes a sphere, we can simply recall that the surface area of a sphere of radius is .

In calculus terms, we would first find an expression for the surface element, which is given by








So the area of the surface is






as expected.

Idon’t see the picture
