keyboard for input.  
Transforming a Manually Input Equation to a Conics Form 
After you manually input an equation on the Conics Editor window, you can use the  
procedure below to transform it to a preset Conics Form.
Example:  To transform the equation                                      to the standard Conics Form

Tip
•  If the equation you input cannot be transformed into the standard Conics Form you selected, the 
message “Can’t Transform into This Type” appears. 
•  An input equation may not transform correctly if it includes a square root calculation or some 
other function.
