What’s on the Uniform Convergence poster
A 5-row table: Question · Pointwise · Uniform.
A sequence of functions fₙ tending to f.
- Definition — N depends on x — One N serves every x
- Limit of continuous fₙ — May be discontinuous — Is continuous
- Swap limit and integral — Not in general — Valid on [a, b]
- Swap limit and derivative — No — Needs fₙ′ uniform too
- Boundedness carried over — No — Yes
xⁿ on [0, 1] converges pointwise to a discontinuous limit. On [0, c] with c < 1 the same convergence is uniform.
Questions about the Uniform Convergence poster
- What’s on the Uniform Convergence poster?
- A 5-row table: Question · Pointwise · Uniform. A sequence of functions fₙ tending to f. Definition — N depends on x — One N serves every x; Limit of continuous fₙ — May be discontinuous — Is continuous; Swap limit and integral — Not in general — Valid on [a, b]; Swap limit and derivative — No — Needs fₙ′ uniform too; Boundedness carried over — No — Yes. xⁿ on [0, 1] converges pointwise to a discontinuous limit. On [0, c] with c < 1 the same convergence is uniform.
- Who is the Uniform Convergence poster for?
- Uniform Convergence belongs to the Mathematics section rather than to a school year, because math is not something one grade owns. Anyone learning analysis can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Uniform Convergence poster?
- Before swapping a limit with an integral, a derivative or another limit. A wall chart earns its place by being glanceable from where the work is happening, so Uniform Convergence belongs on the wall where that math work actually happens, within glancing distance, rather than filed away.
- What other posters go with Uniform Convergence?
- Absolute vs Conditional, Bolzano-Weierstrass and Cauchy Sequences sit alongside Uniform Convergence in the Mathematics section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Absolute vs ConditionalBolzano-WeierstrassCauchy Sequences
- Is the Uniform Convergence poster free to download and print?
- Yes. Uniform Convergence downloads as a free PDF with no account, no email and no watermark, like everything else in the Mathematics section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Uniform Convergence poster print at?
- Uniform Convergence is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Uniform Convergence loses nothing.Printing guide
