6. A common problem of mathematical physics is that of solving the Fredhol integral equation f(x)-ф(x) +1 K(x,t)ф(t)dt, where the functions f (x) and K(x, t) are given and the problem is to obtain ф(x). (a) Describe a numerical method for solving this equation. (b) Solve the following equation דר o(x) x2+/ 3(0.5 sin 3x-ty?)o(t) dt. Compare to the exact solution φ(x) = sin 3x
