Description
Examples
Change(v, c)
Change(v, c, y)
v
-
expression involving definite or indefinite integrals
c
a transformation or a list or set of transformations
y
a list of the new variables
The Change command performs a change of variables in the integrals involved in v.
The second parameter c is the transformation (or list of transformations or set of transformations) in the form x=f(u) (assuming x is the original variable and u is the new variable). Implicit transformations (g(x)=h(u)) can be given as long as it is possible to unambiguously rewrite it as an explicit transformation.
The third parameter y is required only if the number of new symbols in the transformation is not equal to the number of old variables in v.
There are two new symbols in the transformation so the third argument is required.
Multivariate integral.
