I'm really stuck here....
Ältere Kommentare anzeigen
I need to create a program which will ask the user to input a symbolic expression in x, then display the first and second derivatives and graph the (original) expression in an appropriate window and highlight all roots, critical values, and inflection points.
I know to use syms for this, but I'm stuck on this problem.
