Big Karl Posted January 19, 2011 Share Posted January 19, 2011 My Casio fx-9750 GIl gets an "Ma error" if say I plug in sin^-1 8/15. Is there any solution? Can I do it without a calculator? Actually I plugged in .53 instead of 8/15, problem solved. Link to comment Share on other sites More sharing options...
