I want to take v_{r} , v_{theta}, and v_{pi} common out of this expression and I want to simplify in a more simplify way. The maple sheet is attached below:metriccalculaions.mw

 

G[ti] := -(v[r]*`cosθ`*`cosφ`+v[r]*`cosθ`*`sinφ`+v[r]*`sinθ`)*rho*(-c^2+(1-A)*(v[r]^2+v[theta]^2+v[phi]^2-(v[r]*`cosθ`*`cosφ`)^2-(v[r]*`cosθ`*`sinφ`)^2-(v[r]*`sinθ`)^2))/(A*c^3)
