I have some algebraic expression which I want to expand.

I used the ExpandSteps command to show me the steps, but I guess I used it incorrectly.

Attached below the file with the commands.

It should be expanded to -\Delta*\sin^2(\theta), but I want maple to show me the steps.

"with(Student[Basics]): Delta:=r^(2)-2 M*r+a^(2); rho^():=sqrt(r^(2)+a^(2)*(cos(theta))^(2)); ExpandSteps((a^(2)*sin^(2)(theta)-Delta^(2))*((r^(2)+a^(2))^(2)-a^(2 )*Delta*sin^(2)(theta))*((sin^(2)(theta))/(rho^(4)))-(4 *a^(2)*M^(2)*r^(2)*sin^(4)(theta))/(rho^(4)))"

Error, (in Student:-Basics:-ExpandSteps) too many levels of recursion
