Hey people, I know this may seem trivial but i'm having some trouble integrating a function. I have always been weak with integration but this one has a constant and is baffling me! the function to be integrated is:
f(x) = x^2.e^(-Px)
I would really appreciate if anyone could help me solve this one!
Thanks,
Watto
Hey having some more trouble with this problem,
I was asked to numerically integrate the function:
f(x) = x^2.e^(-Px)
between the limits 0 and 2*pi where p=3
On a computer program called MATLAB I have done so using the trapezium and simpsons rule and evaluated the integral as 0.0741 for both with a sufficient number of intervals.
however the proof above seems correct but it gives me an extremely small number for the integral due to e^(-Px) being roughly e^-18.
Can anyone shed some light into where i may have gone wrong?
