Drawing a Graph
u To store a polar coordinate function ( r =) * 1
○ ○ ○ ○ ○
Example To store the following expression in memory area r 2 : r = 5 sin3
θ
3(TYPE)2( r =) (Specifies polar coordinate expression.)
f sdv(Inputs expression.)
w(Stores expression.)
u To store a parametric function * 2
○ ○ ○ ○ ○
Example To store the following functions in memory areas Xt3 and Yt3 :
x = 3 sin T
y = 3 cos T
3(TYPE)3(Parm) (Specifies parametric expression.)
d svw(Inputs and stores x expression.)
d cvw(Inputs and stores y expression.)
* 1 A function cannot be stored into a memory area
that already contains a function of a different
type from the one you are trying to store. Select
a memory area that contains a function that is
the same type as the one you are storing, or
delete the function in the memory area to which
you are trying to store.
* 2 You will not be able to store the expression in an
area that already contains a rectangular
coordinate expression, polar coordinate
expression, X = constant expression or inequality.
Select another area to store your expression or
delete the existing expression first.
