I am aware of Whitney's approximation theorem for manifolds without boundary but I was wondering if there is reference which states the above theorem for manifolds with boundary. Thank you.

  • @MikeMiller thanks a lot So should I delete this question or should I let it stay as it is? – happymath Nov 02 '15 at 03:37
  • It's up to you. Perhaps you could find the precise reference to the appropriate theorem in Hirsch's book and post it as an answer, in case some other weary traveler finds it useful. –  Nov 02 '15 at 03:38

One proof is given in my Introduction to Smooth Manifolds (2nd ed.), Theorem 9.27.
