The terms are used for all three forms of the function.

Non-linear regression is used when the underlying form of the function is known and regression is used only to estimate the parameters of that function.

The field of optimization is further split in several subfields, depending on the form of the objective function and the constraint.

It is based on the form of the function being integrated and on methods for integrating rational functions, radicals, logarithms, and exponential functions.

This is the part which caches the compiled form of the anonymous function, but it can only be invoked by being passed to the apply command.

The goal is to minimize H[m] with respect to the output signal m. The form of the function determines the particular algorithm.

He did not, however, give the exact form of the function, which was later shown to be , where is the absolute temperature of the hotter reservoir.

Note that the form of the function f(t) for constant proper acceleration is well known (see the article hyperbolic motion).

To carry out regression analysis, the form of the function f must be specified.

The exact functional form of the potential function, or force field, depends on the particular simulation program being used.
