Question description

Pretending that the cosine function, cos(x) , is not available in the C compiler, create your own cos(x) using

 cos (x) = 1 - x22! + x44! - x66! + ¼

and demonstrate your program by making a table as:

 x mycos(x) cos(x) 0.0 1.000 1.000 0.1 1.101 1.105 0.2 1.308 1.221 ... ... ... 1.0 1.69 1.781

where mycos(x) is from your program and cos (x) is the C-supplied function in math.h.

Note:

1. The values above are false.
2. The following is the general form of cos (x).
 cos(x) = ¥åi=0 (-1)i x2 i(2 i)! ,
3. Take first 10 terms for the series.

Template:

 ```#include #include int factorial(int n) { (your code here) } float mycos(float x) { float sum=0; int i; for (i=0;i<=10;i++) sum = sum + (your code here); return sum; } int main() { int i=1; for (i=1;i< .......) printf(.......); return 0; } ```
