It is sometimes called the fundamental theorem of numerical analysis.
The fundamental theorem of arithmetic is not actually required to prove the result though.
By Newton's time, the fundamental theorem of calculus was known.
This part is sometimes referred to as the first fundamental theorem of calculus.
This gives it a place among the fundamental theorems of topology.
In 1949 they proved a fundamental theorem of filter synthesis.
In effect, the fundamental theorem of calculus was built into his calculations.
Note also that the case given by the fundamental theorem of algebra is incorporated here.
The fundamental theorem of algebra can be proven from some basic results in complex analysis.
The names are mostly traditional, so that for example the fundamental theorem of arithmetic is basic to what would now be called number theory.
