integration--im lost
how do you integrate this one
[tex]\int sint cosnt dt[/tex]i tried using this identity 1/2 [sin(t-nt) + sin (t-nt)]
then i got stuck so i used another identity again
sin (t[tex]^{+}_{-}nt [/tex])= sintcosnt[tex]^{+}_{-}[/tex]costsinnt
the result is the original equation..
to sum it all, I am hopelessly stuck
