Исправьте программу, а то не получается ничего program jdjd; function f(x: real): real; var d,a,b,x,y,c,e: real; begin d : = 0.8; f : = x - sin(x) - 2 * 3.14 * (1 - d); write; readln (a); write; readln (b); write; readln (e); while b-a> 0 do begin c: =(a+b)/2; if f(z)*f(a)> 0 then a: =c else b: =c; end; write (c); end.
