• 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.
To differentiate the expression X 6 for variable X
Example

u u u u u Tangent Expression —— (tanL)
This command calculates the tangent expression of another expression.
Syntax: tanLine (<expression>, <variable>, <contact point>[)]
<contact point>
....................... The contact point is specified using the <variable> name.
Example To calculate the tangent expression when X = 2 for the
expression X 3

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