Computer algebra systems are invaluable tools for modern researchers. Although commonly used CAS (Maple and Mathematica) are quite slow at numerical computations with extended precision, still they are main workhorses for doing tedious symbolic simplifications and manipulations on expressions.

However, with all the respect to substantial progress in the area, we want to draw attention to one of the not-so-obvious issues with symbolic simplifications – implicit assumptions. In a course of working with expression, symbolic engine makes certain assumptions about variables involved. This process is automatic and very helpful, as it takes this burden from user’s shoulders.

However, as always with any automation, picture is not that idealistic. Implicit assumptions made by software define the result we get, but nevertheless such assumptions are hidden from the user (at least by default) and not easily accessible. In some situations this leads to completely unexpected and wrong results. In this post we show one of the examples.
