Curves - Casio Fx-CG20 User Manual

Curves

With the representation of curves, the influence of parameters are
explained in a function.
In the DYNA- application, families of curves can be dynamically
represented ( see page 32. )
Curves
Should be shown, for example, the function with Parameter K:
f ( x ) = Kx^2 with KЄ{-1,0,5,0,5,1}
Input Syntax:
Functions term, [ Parameter= value, value,..., value ]
Note: It is also possible to enter a list with braces directly as a factor.
{Valu, Value, Value, ...} Functions term.
Graphical representation
Represent the Graph with [ F6 ] The calculation can take a number
of little value.
Analyse the Graph
For analysis ( TRACE, G-SOLV,... ) the graph of the function
is selected with the Cursor keys ( ^ ) ( down ) .
Curves
Use a constant ( all letters except T )
•
• Specify the range of values of the constants:
e.g. K*K^2, [ K=-1,-0.5,0.5,1 ]
• Alternatively, the constant can be directly entered:
e.g. {1,2,3}*x^2
