approximation

In mathematics|lang=en terms the difference between approximation and mollifier

is that approximation is (mathematics) an imprecise solution or result that is adequate for a defined purpose while mollifier is (mathematics) an "approximation to the identity", a smooth function with special properties, used in distribution theory to create sequences of smooth functions approximating nonsmooth (generalized) functions, via convolution.

As nouns the difference between approximation and mollifier

is that approximation is the act, process or result of approximating while mollifier is (mathematics) an "approximation to the identity", a smooth function with special properties, used in distribution theory to create sequences of smooth functions approximating nonsmooth (generalized) functions, via convolution.

As nouns the difference between approximation and overapproximation

is that approximation is the act, process or result of approximating while overapproximation is an approximation that is higher than the true value.

As nouns the difference between approximation and underapproximation

is that approximation is the act, process or result of approximating while underapproximation is an approximation that is lower than the true value.

As a noun approximation

is the act, process or result of approximating.

As an adjective contone is

(printing) having a continuous range of tones from white to black, rather than an approximation such as stippling.

In mathematics|lang=en terms the difference between approximation and linearization

is that approximation is (mathematics) an imprecise solution or result that is adequate for a defined purpose while linearization is (mathematics) a linear approximation of a non-linear system.

As nouns the difference between approximation and linearization

is that approximation is the act, process or result of approximating while linearization is the modification of a system such that its output is linearly dependent on its input.
