i. In variable changes of plane and space integrals, the local magnification ratio of the area or volume is always the same as the Jacobian determinant of the transformation.


ii.
In the variable change of the plane integral, the magnification ratio of the area is constant (i.e. does not depend on the examined point), if the variable change is linear, i.e. x=au+bv, y=cu+dv, when a,b,c,d∈R are constant.


iii.
In the spherical coordinate system, dV=r2sinφdrdφdθ
.
