Testing Solutions Using Casio 9860gii Calculator
I am a teacher and have been encouraging my students to purchase the Casio graphing calculators as they are cheaper than TIs. On the TI -84 calc there is a "Test" feature. My students use this feature to test the solutions they get from manually solving an equation or exponent expression. I am trying to find a similar feature or some way to do the same thing on the Casio. I have searched for hours on the internet and can not find anything. I am aware of the feature for evaluating equations, however that gives my students the answers which defeats my purpose. Any help you can give is greatly appreciated.
