1
Example To store the following expression in memory area r 2 : r = 5 sin3 θ
3 (TYPE)2 ( r =) (Specifi es polar coordinate expression.)
f s d v (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) (Specifi es 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 fi rst.
