Best ResponseYou've already chosen the best response.0Ok.., ok, i've tried. and i got \[T (x,0) \sum_{n=1}^{\infty} a_{n} \sin (nx)\] then into fourier form: \[a_{n} \frac{ 2 }{ l } \int\limits_{0}^{l} f(x,0) \sin (nx) dx\] because of T = f(x,0)= cos x for y =0; then \[a_{n} = \frac{ 2 }{ \pi } \int\limits_{0}^{\pi} \cos x . \sin (nx) dx\] how to solve \(a_{n} = \frac{ 2 }{ \pi } \int\limits_{0}^{\pi} \cos x . \sin (nx) dx\) ?? Would you kinly help me guys ??
