Question

//

#define PI 3.14

double cos_N (double x, int N);
double cos_delta(double x, double delta );
int factorial (int n );
double power ( double x, int n);


//CORRECT ANY ERRORS OR MODIFY ANYTHING .

//NO MATH LIBRARY.

double cos_N (double x, int N)
{
int i;
double sum=0;
if ( x> 0)
{
for(i=1;i<=N;i++)
{
sum=sum+i;
}
}
return sum ;
}

//// I NEED HELP HERE in this delta function....YOU HAVE TO USEfile i/0, LIKE FPRINTF, FSCANF, FOPEN, FCLOSE..A file is going to read

cos_delta(double x, double delta ) .
{

}


int factorial (int n)
{
int Factorial = 1 ;
int i;
for ( i = 1 ; i < =n ; i++ )
{
Factorial * = i ;
}
return Factorial ;
}

double power ( double x, int n)
{
int i;
double p=1;
if(x>0)
{
for ( i = 1 ; i<=n ; i++)
{
p=p*x;
}
}
else if(x<0)
{
for ( i = 1 ; i<=n ; i++)
{
p=p*(-x);
}
}

return p ;
}
