DERIV Derivative and partial derivative

DERIV has two arguments: an expression (or a function)

and a variable.

DERIV returns the derivative of the expression (or the

function) with respect to the variable given as the second

parameter (used for calculating partial derivatives).

Example

Calculate:

Typing:

DERIV(X·Y

·Z

+ X·Y,Z)

gives:

DERVX Derivative

DERVX has one argument: an expression. DERVX

calculates the derivative of the expression with respect to

the variable stored in VX.

For example, given:

calculate the derivative of f.

Type:

Or, if you have stored the definition of f(x) in F, that is, if

you have typed:

then type:
