Using the Interactive Menu

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.

•For details about differential calculations, see “2-7 Using the Action Menu”.

(2)Drag the stylus across “diff(sin(x),x)” to select it.

(3)Tap [Interactive] and then [apply].

•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.
