consider the wave packet psi(x, t=0) = C*exp(i*p0*x/hbar)*exp([x]/(2*deltax))
where C is the normalisation constant part a) normalise psi(x) to unity I took Integral from negative infinity to positive infinity of ([psi]^2)dx and got [C]^2 * ( Integral from negative infinity to 0 of exp(x/deltax)dx + Integral from 0 to positive infinity of exp(x/deltax)dx ) However this gives me [C]^2 * 0 and there is no number for C that i can think of that can make it equal to 1. Im thinking C must be some complex number, but i dont know where to go from here... Note: this is for a introductory QM class

You did the integrals wrong. The result is not 0.
