Homework Statement
if H_n(t)= (-1)^n * e^(t^2) * d^n/dt^n * e^(-t^2)
where n=1,2,...,N
from the orthogonality property of Hermite polynomials we will have:
\int^{\infty}_{-\infty} e^{-t^2} H_n(t) H_m(t)dt = \delta_n,m 2^n n! \sqrt{}pi
this gives
N_n=...
can anybody find the result for the following equation:
F(d)= \int^{T_f}_{0}p(t)p(t-d) dt
where
916; = d but it doesnt appears very well
and
p(t) = (-1)^n * e^(t^2) * d/dt * e^(-t^2)
thanks alot!
By passing warm air through a cotton sock acting as a wick immersed in water, how can I calculate the maximum evaporation to achieve the gratest temperature drop in the air flow? What is the typical formula for temperature drop in evaporative cooling models?
I would like to know how to find the autocorrelation function.
If there are any links for free e-books that can I downloaded to study the autocorrelation function and its properties in details.
Thanks!
