Is there are tutorial anywhere explaining how to use thegraphing calculator?A. There are three into tutorials in the app for the calculator,graph equations, and graph screens. Additional tutorials can befound on our website http://www.mathally.com/Q. How do I get to the keys for pi, e, solve, etc?A. There are four keyboard pages. Each swipe direction across thekeyboard moves you to a different page. The default page is theswipe down page. To get to the page with trig functions, swipeleft. To get to the matrix keys, swipe up. To get to the last page,swipe right. No matter what page you are on, the swipe direction tomove to a specific page is always the same.Q. What do you have planned for future releases?A.
