Isnt worth it

As many have previously stated, this app is quite limited in regards to derivatives. Highly recommend updated version expands upon differentiation and even sign tests. This app simply makes it easier for you to solve systems of equations without being syntax savvy unlike other computational engines such as Mathcad and Mathematica! My advice, learn the input syntax and use the free online solver by wolfram.
