- Derivative[ <Function> ]
- Returns the derivative of the function with respect to the main variable.
- Derivative[ <Function>, <Number n> ]
- Returns the nth derivative of the function with respect to the main variable.
- Derivative[ <Function>, <Variable> ]
- Returns the partial derivative of the function with respect to the given variable.
- Example:
Derivative[x³+3x y, x]
yields 3x²+3y.
- Derivative[ <Function>, <Variable>, <Number n> ]
- Returns the nth partial derivative of the function with respect to the given variable.
- Example:
Derivative[x³+3x y, x, 2]
yields 6x.
- Derivative[ <Curve> ]
- Returns the derivative of the curve.
- Note: It only works for parametric curves.
- Derivative[ <Curve>, <Number n> ]
- Returns the nth derivative of the curve.
- Note: It only works for parametric curves.
Note: You can use
f'(x)
instead of Derivative[f]
, or f''(x)
instead of Derivative[f, 2]
, and so on.CAS Syntax
- Derivative[ <Expression f> ]
- Returns derivative of f with respect to the main variable.
- Example:
Derivative[x^2]
yields 2 x.
- Example:
Derivative[t^3]
yields 3 t2.
- Derivative[ <Expression f>, <Variable a> ]
- Returns derivative of f with respect to the given variable a.
- Example:
Derivative[y x^3, y]
yields x3.
- Derivative[ <Expression f>, <Variable a>, <Number n> ]
- Returns the nth derivative of f with respect to the given variable a.
- Examples:
Derivative[y x^3, x, 2]
yields 6xy.Derivative[x³ + 3xy, x, 2]
yields 6x.
