u To store a polar coordinate function (r=) *1
Example To store the following expression in memory area r2 : r = 5 sin3θ
3(TYPE)2(r=) (Specifies polar coordinate expression.)
fsdv(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.) |
| dsvw(Inputs and stores x expression.) |
| dcvw(Inputs and stores y expression.) |
*1A 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.
