Method Detail

evaluateArg1

public IExpr evaluateArg1(IExpr arg1)

Overrides:

evaluateArg1 in class AbstractTrigArg1

set

protected void set(java.util.ArrayList<IInteger> a,
                   int n)

Compute a coefficient in the internal table.

Parameters:

n - the zero-based index of the coefficient. n=0 for the E_0 term.

eulerE

                       int n)

The Euler number at the index provided.

Parameters:

n - the index, non-negative.

Returns:

the E_0=E_1=1 , E_2=5, E_3=61 etc

setUp

public void setUp(ISymbol symbol)
           throws SyntaxError

Description copied from class: AbstractFunctionEvaluator

Specified by:

setUp in interface IEvaluator

Overrides:

setUp in class AbstractFunctionEvaluator

Parameters:

symbol - the symbol which should be set up

Throws:

SyntaxError
