Hi, I’m working on a set of shell-pages for my team so they can plug them into activities they create. The two slides in this activity are for explicit and implicit equations, depending on needs.
In both, my general method for checking equation accuracy is the evaluate at three (more if needed) points (X,Y) give an answer OTHER than 0 when totaled.
For explicit functions, I just compare F(X), the student input evaluated at three test points X to f(x), the teacher-defined answer.
My ‘correct’ sink is in my equation input, and reads whether my Check number is =1 or =0.
It works inside my graphing calc, but when the correct answer is typed it displays a grey dot instead of a grey check. It does definitively display incorrect answers.
Is there something I missing to get that grey checkmark to appear or am I stuck with a grey dot?
