Thread: While Loop Problem

well fabs is like abs but for floating point numbers, it sort of helps, but I need to sort more things out with this loop and the conditional statement..

Ok, I pretty much give up, I hope to hear from any of you that might be able to help, here is some more fun output..
I edited the while loop again so it gives me even more results, what I have isn't very nice and I don't know, I'm going to make sure the instructor sees what is wrong but if any of you can help, it will be nice. here it is.

Code:

double sine(double x, double precise)
{
	double term = 1;
	int k = 1;
	double sum = 0;
	do 
	{
		cout << "k: " << k << endl;
		cout << "multiplier: " << power(-1, k+1) << endl;
		cout << "power: " << power(x,2*k-1) << endl;
		cout << "factorial: " << factorial(2*k-1) << endl;
		cout << "fabs: " << fabs(term) << endl;
		cout << "term: " << term << endl;
		cout << "sum: " << sum << endl;
		cout << "sin: " << sin(x) << endl << endl;
		
		term = (power(-1, k+1) * (power(x, 2*k-1)/factorial(2*k-1)));
		sum = sum + term;
		k= k+1;
	}while ((fabs(term)<precise) || (k<10));
	return sum;
}

Hi, welcome to the Sine Function
Please enter a angle for the Sine Function
4
To what precision?
.001
Is the value in degrees or radians?
If the value is in degrees, type 'degrees', otherwise you
may type anything else.
no

Ok thanks all! night!

I was told by a certain poster here that "Salem would come. Salem would fix your problem". Thank you man, I really appreciate it. I'm going to study this in depth tommorow to really understand what you changed, I'm very tired now, but you helped me out a TON! THANKS
