Learning should always be free...

Hi, here's the code I wrote to compute sinx in C++, but it doesn't give me the correct value.

# include <iostream>
# include <math.h>
using namespace std;

int main()
{
	int count=1;
	double x;
	double sine, num, dem, sign, term;
	sine=0;
	sign = 1;
	
	cout << "Get x: ";
	cin >> x;
	num = x;
	dem = count;
	
	while ( count <= 10 )
	{
		term = (num/dem);
		sine = sine + term*sign;
		num = num*x*x;
		count = count + 2;
		dem = dem * count * (count-1);
		sign = -sign;
	}
	
	
	cout << "The result is: ";
	cout << sine;
	return 0;
}	

The problem I see in this code is that, you forgot to convert the given values from degree to radians. This algorithm works for radian angles. That is the initial problem I saw. Even after that, you could not get the right answer, let me know.

# include 
# include 
using namespace std;

double sin_value( double x);
double x;
double value;
int main()
{

cout << "Welcome!";
cout << "Let's calculate sine value. " << endl;
cout << "Enter value x: ";
cin >> x;
value = sin_value(x);

cout << "The value is: ";
cout.setf(ios::fixed);
cout.setf(ios::showpoint);
cout.precision(10);
cout << sin_value(x);
return 0;
}

double sin_value( double x)
{
int count=1;

double sine,num,term,dem;
num=x;
dem=count;
sine=0;

while ( count <= 10 )
{
	term=(num/dem);
    term = ((-term) * x * x) / (count * (count-1));
    sine =sine + term;
    count = count +2;

}

return (sine);  
}
