• This executes the part of the calculation you selected in step (2). The part of the
calculation that is not selected (× cos(x) + sin(x) × diff(cos(x),x)) is output to the
display as-is.
Using the “apply” Command
The “apply” command is included on the [Interactive] menu only. You can use this command
to execute only a specific part of an expression and display its result.
Example: To calculate the result of diff(sin(x),x) × cos(x) + sin(x) × diff(cos(x),x), and then
calculate only part of the expression
Note
• This procedure assumes that your ClassPad is configured with the following mode settings:
Algebra, Complex, Radian.
u ClassPad Operation
(1) Input the example calculation provided above and execute it.
