x = rsinAcosB

y = rsinAsinB

z = rcosA

show that, using partial derivatives that

d(x,y,z) = r^2 sinA

d(r,A,B)

cheers, i got upto here.

d(x,y,z) = I sinAcosB rsinAcosB -rsinAsinB I

d(r,A,B) I sinAsinB rcosAsinB rsinAcosB I

I cosA -rsinA 0 I

= [(sinAcosB)(rcosAsinB)] - [(sinAsinB)(rcosAcosB)]

but i dont know what to do next in order to show that

d(x,y,z) = r^2sinA

d(r,A,B)
