Got it... the equation 6.16,17 are derived from beta function β (z,w).. which has a relation with gamma function and ultimately in terms of factorial.. The books you guys recommended worked for me! thanks for the help.. now i can continue! :)

thanks guys for replying.. I am grateful.. yet I have not taken a course in which gamma functions were included so a little help in evaluating eq. 6.16,17 would be appreciated!

thanks for replying .. I know this is the integral.. I was asking about how can we transform it into this factorial form.. any help in that regard?

Integration formula?? I am a graduate student and during my research I have come across this integration formula shows in attached image file. Can anyone help me make sense of this equation because i couldn't find any help from the literature regarding this equation. Li and Lj are shape...

So this is a reverse step?

I am trying to understand an example from my textbook "applied finite element analysis" and in the variational calculus, Euler lagrange equation example I can't seem to understand the following derivation in one of its examples ∫((dT/dx)(d(δT)/dx))dx= ∫((dT/dx)δ(dT/dx))dx= ∫((1/2)δ(dT/dx)^2)dx...
