The 3 pages that link to Weierstrass M-test, each with the reason it gives.

• Uniform convergenceRelated: It supplies a practical sufficient condition for uniform convergence of series.

• Weierstrass approximation theoremCompared with: Despite the shared name, this is a separate uniform-convergence theorem, not an approximation result.

• Abel's theorem (power series)Compared with: It offers a stronger route to exchanging limits, unlike the boundary argument needed here.
