When I am trying to symbolicly evaluate an integral..it says "pattern match exception" and highlighted my expression in red.
What should I do?
the integral was to find the average momentum
of a harmonic oscillator
the wavefunction is C* x^2 *exp(ax^2)*exp(-b*i*t)
where C,a,b are just some real constants, x is position, and t is time. i is the imaginary number
I tried to put in the whole expression explicitly in the definite integral (integrating from negative infinity to infinity) .
but it gives me ""pattern match exception" and highlighted my expression in red as mentioned.
I tried to define the expression in a different name but it still does not work..
I cannot even take the derivative of my wavefunction w.r.t. x symbolicly.
Please let me know what is the correct way to do this.
I want the result to be symbolic...*sigh.
thank you
