After some integration, i am getting a form [itex]e^{i \alpha\phi+i\beta\phi\sin(\phi-\phi')-i\gamma\sin\phi} [/itex], where ##\alpha, \beta, \gamma## are constants. Now i want to apply the limit where ##\phi ## ranges from 0 to ##\infty ## (ya, in the argument of sine we will encounter ##\infty ## which is exactly my problem). How can i do that?(adsbygoogle = window.adsbygoogle || []).push({});
