[tex] \int_{0}^{\pi/2}(cos(\theta)*exp(-2[\pi(1-cos(\theta))]^2)/k^2)/erf(2\pi/k) [/tex]
Where of course the error function erf is defined as:
[tex]
erf(x)=2/\pi\int_{0}^{x}exp(-t^2)dt
[/tex]
Anyway... this is the problem I want to integrate. I am not looking for someone to post a solution. My question is simply what is the best way of tackling this monster. My first thought is to expand each of the functions into a power series and use the "crank the handle" method. Not very elegant. Can anyone see a better/quicker method?
Thanks
Harry
