Hi, Namir,

There's a number of errors in your program's listing, namely wrong numeration of the lines marked in red below:

Besides, several of your 10-digit numeric coefficients below marked in red are wrong or inaccurate ...

... so you'd do well getting the correct/accurate values from a reputable source and/or typing them correctly.

Finally, if you'd take a friendly advice, when posting a program which performs such a computation, it would be proper (nay, mandatory) to include some numeric results generated by the program, if nothing else just that people trying it out can be reassured that it's correctly loaded and properly working by simply running your program and actually getting exactly your results.

Regards.
