Antimatter Annihilation Produces tremenndous energy.where does this energy come from??

grt goin man!!!!

see V(sinx )is actually higher level maths,it has lots of analyses and can be done by sinx series,but it is a diverfgent function and so it has errors.but for +2 level this is the soln,but it is not correct as u would know after doin higher studies

let sinx=z^2        cosxdx=2zdz        dx=2zdz/cosx,i.e.,dx=2zdz/(1-z^2)^(1/2)

I=z^2dz/(1-z^2)^(1/2)       I= -(1-z^2-1)dz/(1-z^2)^(1/2)
I= -(1-z^2)^(1/2)dz +dz/(1-z^2)^(1/2)
now use the appropriate intgration by parts special form formulas 2 get the answer.
cheers
