помогите написать программку в С++. со всеми библиотеками и со всем

1.

include lt;iostreamgt;

include lt;cmathgt;

using namespace std;

int main()

double x = 0.4 * pow(10, 4);

double y = -0.875;

double z = абс(cos(x) - cos(y));

z *= (1 + y + (pow(y, 2)/2) + (pow(y, 3)/3) + (pow(y, 4)/4));

cout lt;lt; z;

return 0;

2.

include lt;iostreamgt;

include lt;cmathgt;

using namespace std;

int main()

double a = -0.5;

double b = 1.7;

double t = 0.44;

double y = exp(-b*t) * sin(a*t+b);

y -= sqrt( абс(b*t + a) );

double s = b * sin(a*t*t * cos(2*t));

cout lt;lt; "y: " lt;lt; y lt;lt; endl;

cout lt;lt; "s: " lt;lt; s;

return 0;
