More importantly, in order to eliminate this type of typo, the top-level
var binds the declared variables to names in the global namespace already.
Thus, the only statement you need is
var('dr r1 r2 lda dphi_0')
If the binding behaviour is not desired then use a different "var". For
instance:
dr, r1, r2, lda, dphi_0 = SR.var('dr r1 r2 lda dphi_0')
