Homework Help: Probabilitry of finding particle between

    Probabilitry of finding particle between....

    1. The problem statement, all variables and given/known data
    A particle with some potential has a wavefunction of [itex]\Psi[/itex]=Axe-kx(from 0 to infinity) if k=.5 what is the prob of finding particle between x=2.0 and 2.1 Angstrom.


    2. Relevant equations
    P=[itex]\int[/itex] [itex]\Psi[/itex]2


    3. The attempt at a solution
    I already found what A= in a different problem its 2k3/2
    So i thought i would just plug in for A and do the integration from 2 to 2.1. Thats what some example did. i get like .1005 but the answer is .0271.

    thanks
