ALGBR Mode Commands
u u u u u Integration —— ( ( )
This command can be used to determine the primitive function or calculate the
definite integral for an expression.
Syntax 1: (<expression>, <variable> [, <integration constant>] [)]
Syntax 2: (<expression>[, <variable>, <integration constant>] [)]
Syntax 3: (<expression>, <variable> , <start>, <end> [)]
• A default variable of X is used when specification of a variable is skipped in
• Syntax 3 calculates the definite interval in accordance with the specified
• Multiple integral calculations can also be performed.
Example
• A default value of 0 is automatically assumed for the integration constant.
u u u u u Differential —— (diff)
This command can be used to determine the derivative or calculate the value of
the derivative for an expression.
Syntax 1: diff (<expression>, <variable>, <
Syntax 2: diff (<expression>, <variable>[, <
Syntax 3: diff (<expression>[, <variable>, <
<integration constant> ........... Integration constant
<start> ............ Start point of the integration interval
<end> ............. End point of the integration interval
Syntax 2.

Inputting a symbol name such as C for the integration constant produces a
result in a form that is the same as the indefinite integral.
