To define the 1. Display the Symbolic view (| symb |). If the highlight is on

expression an existing expression, scroll to an empty line—unless you

don’t mind writing over the expression. Or, clear one line

(I DEL I) or all lines (■ [CLEAR]).

2. Make sure your function is in the form “y = For example,

given the equation 9x+y - 11=0, you would rearrange it

to y = f(x) = -9x + 11. Type in just the expression

(-9x+l 1) for the right side.

• For a Function definition, enter an expression to

define F(X). The only independent variable in the

expression is X.

» For a Parametric definition, enter a pair of

expressions to define X(T) and Y(T). The only

independent variable in the expressions is T.

® For a Polar definition, enter an expression to define

R(0). The only independent variable in the expression

is 0.

e For a Sequence definition, enter the first, second, and

nth terms for U (U1, or...U9, or UO). Define a sequence

function in terms of N or of the prior terms, U(N -1)

and U(N -2). The expressions should produce real

valued sequences with integer domains.

3. Press I ENTER I or {{OK}} to enter the expression into the list.

All checkmarked expressions mill be plotted.
