Not a good app

1st of all, the trial is too short for this app to be worth downloading. You get like 4 problems solved for free before you have to upgrade to premium. 2nd, its confusing. All I wanted was for it to solve an trigonometric equation (which the description says it can do) and it kept expanding it even after I changed the setting. This app was a waste of time and is causing me more stress than the problem Im trying solve.
