Normalizing wavefunction

  1. Sep 12, 2015 #1
    Hello, please help me with normalization problem..

    f is sin(Pi x/L) between 0, L

    first we use normalization formula and integrate N^2 Sin^2(pi x/L) to get N^2( L/2) Sin L/2 which equals to one ..... this is my solution

    in the textbook his result is N^2 (L/2)

    My question is how he get rid of Sin L/2.. please explain

    Hello, and welcome to PF!

    Sin L/2 is incorrect. Check your work.
