Advanced Graphing ?

[Han]

Did you mean to shade in the area between the x-axis and the function max(cos(x),sin(x))? If so, then define F1 as MAX(SIN(X),COS(X)) and then in the advanced graphing app use:

V1: Y \( \ge \) F1(X) AND Y\(\le \) 0
V2: Y \(\le \) F1(X) AND Y \( \ge \) 0

Edit: If you want them to be of the same color (say using V1's color), then do:

V2(COLOR):=V1(COLOR);
