Description

in the PICTURE menu):

R 0 0 T

Root. Moves the cursor to a root (intersection of the

function and the r-axis) and displays the value of the

root. If the root is not in the display window, briefly

displays the message OF-F SCREEN before displaying

the value of the root. If there are multiple roots, the

root-finder usually finds the root closest to the current

cursor location. For an equation, it searches for a root

of the expression on the right side of the equation.

Intersection. If only one function is plotted, moves the

cursor to a root (same as ROOT ). If two or more

functions are plotted, moves the cursor to the closest

intersection of two functions and displays the {x,y)

coordinates. If the closest intersection is not in the

display window, briefly displays the message OFF

SCREEN before displaying the coordinates of the

intersection.

S L.. iJ P E

Slope. Calculates and displays the slope of the function

at the r-value of the cursor, and moves the cursor to

the point on the function where the slope was

calculated.

|~| h; P H

Area. Calculates and displays the area beneath the

curve between two r-values defined by the mark and

cursor. (Before you execute this operation, press to

mark one end of the x interval, then move the cursor

to the other end.)

Shade. If only one function is plotted, shades the

region between the r-values defined by the mark and

the cursor, between the function and the r-axis. If

there are two functions plotted, shades the region

between the two functions, and between the r-values

defined by the mark and the cursor.
