Dear guys

I would like to find the graph of the following function

let $$v(x)=\int_{-\infty}^{\infty}[\int_{0}^{\infty}t^{\alpha}e^{-t^{2}/2 +\kappa(b-y)t}dt(\int_{0}^{1}\frac{u^{\beta}}{(1-u^2)^{1/2}}e^{\frac{-\gamma[(x-b)u+(b-y)]^2}{(1-u^2)}}du)]dy$$

where $\alpha$ is any real number, $\kappa,b,\beta,\gamma\in (0,\infty),$

I know it is impossible to find the integral. What I did by far is :

Approximate the integral $$(\int_{0}^{1}\frac{u^{\beta}}{(1-u^2)^{1/2}}e^{\frac{-\gamma[(x-b)u+(b-y)]^2}{(1-u^2)}}du)$$ by Simpson method, or Newton-cotes method

Approximate the integral $$\int_{0}^{\infty}t^{\alpha}e^{-t^{2}/2 +\kappa(b-y)t}dt $$

Approximate the integral by plugging what I have in 1) and 2)

Graph the function

but using approximation methods I know are good enough.I meant the error is so big It would be great if some one could tell me a good method to find the graph of the above function

many thanks !
