Constructor Details

Sech

public Sech(GeneralFunction operand)

Constructs a new Sech

Parameters:

operand - The function which sech is operating on

Method Details

getDerivative

public GeneralFunction getDerivative(String varID)

Description copied from interface: Differentiable

Returns the derivative of a GeneralFunction with respect to a variable. Should not be used in general; GeneralFunction.getSimplifiedDerivative(java.lang.String) is strongly preferred.

Parameters:

varID - the ID of the variable that is differentiated against

Returns:

the derivative of the function with respect to varID

evaluate

public double evaluate(Map<String,Double> variableValues)

Returns the hyperbolic secant of the stored UnitaryFunction.operand evaluated

Parameters:

variableValues - The values of the variables of the GeneralFunction at the point

Returns:

the sech of UnitaryFunction.operand evaluated

getInstance

public UnitaryFunction getInstance(GeneralFunction operand)

Description copied from class: UnitaryFunction

Returns a new instance of this UnitaryFunction

Specified by:

getInstance in class UnitaryFunction

Parameters:

operand - the GeneralFunction to be operated on

Returns:

a new instance of this UnitaryFunction

getElementaryIntegral

public GeneralFunction getElementaryIntegral()

Description copied from interface: Integrable

Returns the elementary integral of the function. Ex: sin(2x) becomes -cos{2x}, NOT -cos(2x)/2.

Returns:

the elementary integral of the function as specified above

getInverse

public Class<?> getInverse()

Description copied from interface: Invertible

Returns the Class corresponding to the inverse of this function

Returns:

the inverse Class

simplifyInverse

public GeneralFunction simplifyInverse()

Description copied from class: UnitaryFunction

If UnitaryFunction.operand is an instance of the inverse of this function, returns operand.operand

Overrides:

simplifyInverse in class UnitaryFunction

Returns:

operand.operand if UnitaryFunction.operand is an instance of the inverse, and this otherwise
