uIntegration —— ( ( )
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> [)]
<integration constant>...........Integration constant
<start> ............ Start point of the integration interval
<end> ............. End point of the integration interval
• A default variable of X is used when specification of a variable is skipped in
Syntax 2.
• Syntax 3 calculates the definite interval in accordance with the specified
integration interval.
• Multiple integral calculations can also be performed.
Example To integrate the expression X
2
for variable X
4(
∫
( )vx,vw
• A default value of 0 is automatically assumed for the integration constant.
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.

uDifferential —— (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>, <
nth>[, <differential coefficient>] [)]
Syntax 2: diff (<expression>, <variable>[, <nth>, <differential coefficient>] [)]
Syntax 3: diff (<expression>[, <variable>, <nth>, <differential coefficient>] [)]
<
nth> .............. Specifies differential of nth order. n must be a positive integer.
<differential coefficient>
....................... Any value specified as the differential coefficient is substituted
in the function for calculation of the result.
