Notes •You can use any alphabetic character from A through Z as a variable in an equation, except for X, Y, T, r, and O. *If there is not enough memory to store your equation, an error (Mem ERROR) occurs. When this happens, press RD to clear the error message. *If there is no variable in the formula you input, the message "No variable" appears on the display. When this happens, press m, clear the error message. 10-3 Editing a Function Use the following procedures to modify a function that is already stored in memory to create a new one. Important •When you edit a function to create a new one, the original function is deleted. • To edit a function Example To change the second function stored in memory from Y = A (X + B)2 + C to Y = A (X + B)2 - C: Specify the function you want to change. 0 DYNAMIC GRAPH Y=AX+E EfirgeOaSi E(EDIT) 000 Save the new equation.
