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.

integration interval.

To integrate the expression X 2 for variable X

4( ( )vx,vw

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.

th> .............. Specifies differential of

....................... Any value specified as the differential coefficient is substituted

in the function for calculation of the result.
