A particular calculation produces at an early stage the intermediate result p1 = (Sin[x]/x) + (Sinh[y]/y) , (x and y both real) and this result then feeds into further expressions in a lengthy symbolic calculation. When I try to do any numerical evaluations of the final expressions with either x or y = 0, I get "Indeterminate expression" or "infinity 1/0" error messages, even though the expressions themselves, like the expression above, are perfectly determinate and finite for those limits. Any simple way to make this expression behave as it should under numerical evaluation?
