Trabajo #3
1. La función coseno viene definida mediante el siguiente desarrollo en serie de Taylor.
#include <iostream>
#define PI 3.141592654
using namespace std;
double Seno(doublex){
int s = 1, pot = 3, den;
double n, num = 1, sum;
n = PI * x / 180;
sum = n;
for(int i = 0; i < 4; i++){
den *= pot * (pot - 1);
sum += (num / den) * s;s *= -1;
num *= n * n;
pot += 2;
}return sum;
}double Coseno(double x){ double pot = 2, num, den = 1.0, n, sum;
int s = -1; n = PI * x / 180;
sum =1;
num = n * n; for(int i = 0; i < 5; i++)
{den *= pot * (pot - 1.0);
sum += (num / (den * s));
s *= -1;
pot += 2;
num *= n * n;}return sum;
}int main()
{ double x;
int resp;d{cout << "\n1. Seno\n2. Coseno\nElija: "; cin >> resp;
}while(resp != 1 && resp != 2);cout << "Ingrese el valor de x:";cin >> x;
if(resp == 1)
cout << "sin(" << x << "): " << Seno(x) << endl;
else cout << "cos(" << x << "): " << Coseno(x)<< endl;
system("pause");
return 0;}
2. Escribir un programa que mediante un menú permita gestionar las operaciones suma, resta, producto y cociente de fracciones.#include<iostream>
using namespace std;
double suma(double a, double b){
double s1;
s1=a+b;
return (s1);}
double resta(double a, double b){
double s2;
s2=a-b;return (s2);}
double producto(double a,double b){
double s3;
s3=a*b;
return (s3);}
double cociente(double a,double b){
double s4;
s4=a/b;
return (s4);}int main (){
double a1,b1;
int n;
cout<<"elija una opcion :"<<endl;
cout<<"(1) suma "<<endl;
cout<<"(2) resta "<<endl;
cout<<"(3)...
