(C.F.) "The additions such as step by step exact DE, step by step homogeneous and step by step bernoulli are fantastic and would definitely make differential equations made easy an excellent study tool for anyone. Or it can be used as a quick solver to check steps. I think it's the best software of it's kind."
(A.M.) "I just have to give it to you guys for the great job you are doing. I was using the salt in tank program and it works flawlessly, its beyond everything I expected."
(J.P.) "I highly recommend DME, it is unlike anything else out there. The ability to solve nearly any first and second order differential equation makes almost as powerful as a computer. Great for solving HW problems and the step-by-step function helped me to find my mistakes, which makes it better than a computer! I love the phase line tool and the step-by-step Inverse LaPlace function. It is a great learning tool."
