Первая программа
var x,y: real;
begin
read(x);
y := x-Power(x,3)/3+Power(x,5)/5;
write('y = ', y );
end.
Вторая
var x,y: real;
begin
read(x);
y := Power(2, -x)-cos(x)+sin(2*x*y);
write('y = ', y );
end.
Третья
var x,y: real;
begin
read(x);
y := (Power(x,2)-7*x+10)/(Power(x,2)-8*x+12);
write('y = ', y );
end.
Четвертая
var x,y: real;
begin
read(x);
y := x-10*sin(x)+abs(power(x,4)-power(x,5));
write('y = ', y );
end.
