Integration —— ( ( )
This command can be used to determine the primitive function or calculate the
definite integral for an expression.
Syntax 1:
∫
(, [, ] [)]
Syntax 2:
∫
([, , ] [)]
Syntax 3:
∫
(, , , [)]
........... Integration constant
............ Start point of the integration interval
............. 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 X2 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.

Differential —— (diff)
This command can be used to determine the derivative or calculate the value of
the derivative for an expression.
Syntax 1: diff (, , < n th>[, ] [)]
Syntax 2: diff (, [, < n th>, ] [)]
Syntax 3: diff ([, , < n th>, ] [)]
< n th> .............. Specifies differential of n th order. n must be a positive integer.
....................... Any value specified as the differential coefficient is substituted
in the function for calculation of the result.
