template<class Base >
void CppAD::forward_sin_op_0 ( size_t  i_z,
size_t  i_x,
size_t  nc_taylor,
Base *  taylor 
) [inline]

Compute zero order forward mode Taylor coefficient for result of op = SinOp.

The C++ source code corresponding to this operation is

	z = sin(x)

The auxillary result is

	y = cos(x)

The value of y is computed along with the value of z.

Template Parameters:
Basebase type for the operator; i.e., this operation was recorded using AD< Base > and computations by this routine are done using type Base .
Parameters:
i_zvariable index corresponding to the last (primary) result for this operation; i.e. the row index in taylor corresponding to z. The auxillary result is called y and has index i_z - 1.
i_xvariable index corresponding to the argument for this operator; i.e. the row index in taylor corresponding to x.
nc_taylornumber of colums in the matrix containing all the Taylor coefficients.
taylorInput: taylor [ i_x * nc_taylor + 0 ] is the zero order Taylor coefficient corresponding to x.
Output: taylor [ i_z * nc_taylor + 0 ] is the zero order Taylor coefficient corresponding to z.
Output: taylor [ ( i_z - 1 ) * nc_taylor + j ] is the j-th order Taylor coefficient corresponding to the autillary result y.
Checked Assertions
  • NumArg(op) == 1
  • NumRes(op) == 2
  • i_x + 1 < i_z
  • j < nc_taylor
