Re: intersection of 2 functions



Put the functions in y1 and y2 (or y3 or y4 or y(anything) if need be,
doesn't matter), set the appropriate window, and hit F5 ('GRAPH'). After
it's done graphing, go to the hit MORE and F1 ('MATH'), and MORE and F3
('ISECT'). This is the Intersect feature. There should be an crosshair
at the x-center of your graph (it might be off the screen). Move left
and right until you come closest to the intersection that you want, and
hit enter. Do the same again for the 'second curve'. Up and down will
switch functions if it's on the wrong one. Then put the cursor on the
intersection again and hit enter for the 'guess'. Wait a few moments,
and the x and y coordinates of the intersection will appear at the
bottom of the screen.
