Hello, Sorry to say it but in my opinion you are handling the problem the wrong way. Learn first how to use the basic functionalities of the calculator. The calculator has no need to learn your trigonometry formulas. They are already programmed in its ROM. If YOU need to remember the formulas, it is in YOUR memory that they should be stored.
You can download the complete set of manuals available for this calculator by clicking on this link . There are 22 different chapters each describing a function in detail. Download all the chapters and save them for future reference.
Hope this solves your problem. Thanks
