How to use? There are many ways:

Input or click sin(x) , click for integration, click button for derivative to check its result, click again for second derivative, click to inverse a function, click for definition, click to simplify, click ......
Input the unkown y as seond argument,
o sin(x)=cos(y), y
then click the button to solve for unknown y.
Input command by use of the first function as command, e.g.
- integrate sin(x) as x from 0 to 1
then hit the button or the ENTER key in your keybord.
Input function, e.g.
- int(sin(x))
Input function by use of "," or ";" as separator for multistatements, e.g.
- int(sin(x)), d(sin(x))
Input question mark ? to show a list of function, i.e.
- ?
Input function and question mark ? to show its function source. e.g.
- sin(x)

The same color buttons are a pair of inverse operators, its result can be checked each other if it returns origial function or not. Usual keywords are lowercase, which are different from uppercase, e.g. sin is different from Sin. Its default variable is small letter x, but its default index variable in discrete math is k.
