    Pointwise convergence

    Some animations to illustrate what pointwise convergence is and some counter-examples regarding this notion.

    • Boundedness is not preserved by pointwise convergence.

    • Continuity is not preserved by pointwise convergence.

    • Differentiability is not preserved by pointwise convergence.

    • fn converges does not imply f'n converges

    • Integration counter-examples : Witch's hat functions

    • Integration and uniform convergence
