1) Write an algorithm to calculate the sum of the
following series:
Sum =x-x3/3!
+ x5/5! – x7/7! +……. Stop when
the
term<0.0001.
2) An internet service provider charges
its subscribers per month as follows:
Data usage
(n), in
gbs
charges (NIS)
0.0<n<=1.0
250
1.0<n<=2.0
500
2.0<n<=5.0
1000
5.0<n<=10.0
1500
n>10
2000
Write a C program
to read the usage(n) from a file and print the charges to be paid
by the subscribers.
Your program
must include the function calculate that accept the data usage (n)
and returns the charge/month.

ANSWER
#include<stdio.h>
#include<math.h>
int main()
{
float n;
printf("Enter the valu of x : ");
scanf("%f",&n);
float acc = 0.0001, den, sinx, sinval;
n = n * (3.142 / 180.0);
float x1 = n;
sinx = n;
sinval = sin(n);
int i = 1;
do
{
den = 2 * i * (2 * i + 1);
x1 = -x1 * n * n / den;
sinx = sinx + x1;
i = i + 1;
} while (acc <= fabs(sinval - sinx));
printf("\nResult : %f",sinx);
