c(Max) ... Local maximum value

d(Min) ... Local minimum value

e(Y-lcpt) ... y-intercept

f(Isect) ... Intersection of two graphs

g(Y-Cal) ... y-coordinate for given x-coordinate

h(X-Cal) ... x-coordinate for given y-coordinate

i(∫dx) ... Integral value for a given range

3. When there are multiple graphs on the screen, the selection cursor (k) is located at

the lowest numbered graph. Use the cursor keys to move the cursor to the graph you

want to select.

4. Press w to select the graph where the cursor is located and display the value

produced by the analysis.
