In going through math and physics textbooks, I like to use Mathematica Home Edition 10.2 to input the equations. It would be helpful to be able to solve an equation by single stepping through the solution, to see how the solution was arrived at. Any way to single step?
The way that Mathematica solves an equation looks nothing at all like what a human would do and doesn't have any educational value for most people.
Wolfram|Alpha however can provide step-by-step solutions. You can use Wolfram|Alpha through your web browser, through your phone or tablet, or through Mathematica. Step-by-step solutions are a Wolfram|Alpha Pro feature, but you shoul dbe able to use them in Mathematica.
An example of how to use it:
type "==" and then "Solve y'[x]==Sin[x]". This is how you do a Wolfram|Alpha query in Mathematica. You will then see a button next to the solution that says "Show steps".
