def functions on advanced graphing
Hello, I want to define two functions for the application advanced graphing from history view.
purge(X,Y); from HOME V1(X,Y):=X2*Y=7; V2(X,Y):=5*X3*Y=2; returns Error: Invalid input from CAS V1(X,Y):=X2*Y=7; V2(X,Y):=5*X3*Y=2; returns (X,Y)>false,(X,Y)>false solve([V1(X,Y),V2(X,Y)],[X,Y]) returns [X,Y] ? although pressing the SYMB button the definitions of the functions are well defined How can I define or externally delete the variables of the applications?
