• Syntax 1 determines the derivative in accordance with a specified expression,
variable and order. Specifying a differential coefficient calculates a result in
accordance with the input value.
• A default order of 1 is used when specification of the order is skipped in Syntax
2.
• A default variable of X is used when specification of a variable is skipped in
Syntax 3.
Example To differentiate the expression X6 for variable X

Solve —— (solve)
This command calculate solutions for an expression. Solutions are displayed as
mathematical expressions.
Syntax: solve ( [ =] [, ] [)]
The second expression can be preceded by any of the following operators: =
(equals), < (less than), > (greater than),
