Isolate

Function: isolate (<expr>, <x>) Returns <expr> with subexpressions which are sums and which do not contain <var> replaced by intermediate expression labels (these being atomic symbols like %t1, %t2, ...). This is often useful to avoid unnecessary expansion of subexpressions which dont contain the variable of interest. Since the intermediate labels are bound to the subexpressions they can all be substituted back by evaluating the expression in which they occur.

eq1:2.22*10^-2*sqrt(((PA-PB)*D^4.8)/(S^0.8*L))-Q^0.9;
isolate(eq1,PB);

exptisolate (default value: false) if true will cause isolate to examine exponents of atoms (like %e) which contain <var>.

isolate_wrt_times if true, then isolate will also isolate with respect to products. See isolate_wrt_times.

Do example (isolate) for examples.

There are also some inexact matches for isolate. Try ?? isolate to see them.
