Numerical Analysis Questions & Answers  


I don't understand. Are you trying to code a sin(x) function? If so, there is no need to code it because the function sin(x) is already defined in the math library.






Are you getting the same problem when solving it by hand? If not, then it means there is a bug in your C code. If yes, then outline the problem in another question below.




No, you shouldn't be using pivoting here because the question asks to use Gaussian elimination. Double check your solution: if you think there is a mistake in the question formulation then outline your full solution below in LATEX until the problem occurs and I will check it.




No, I asked that you post the solution by hand and show at which step there is a problem (using LATEX).
