I've been taking this numerical analysis class for 6 weeks. I should be getting an A+ in the class based on my understanding of the material and how hard I work. However right now I only have a B.(I've working my ass off to boost my medicore gpa)

On the midterm there was a proof where we had to calculate the spectral radius of the Gauss-Seidel iteration matrix to determine whether it converges. So I wrote down "The Gauss-Seidel process converges for the matrix A if and only if the spectral radius of the iteration matrix is less than 1." then i proceeded to calculate the spectral radius and got 5 as an answer. He marked off 3/10 points and the reason was I didn't specifically state whether it converges.

I also got 4 more points marked for for similar reasons on the midterm. I tried arguing about them with him but he wouldn't give me a single point back.

Now about the homework. On the first assignment he did the first problem for us. (It was just a 1 line code for calculating the Frobenius norm.) The second part of the problem required us to write a code to calculate the number of steps it takes the Frobenius norm of a certain iteration matrix to covert to a certain value. He gave me a 0 on that problem because I didn't send him the Frobenius norm code as a separate file.(in matlab) because I figured that it would just be a part of the code of the second problem.

On the second assignment. I was given zeros on my solutions because I sent him the answers by e-mail instead of writing them down on a piece of paper. I sent him my code and solutions 2 days in advance and asked him in the e-mail whether we could submit our solutions electronically. (His reply was that he didn't check his email until the deadline. And he marked me off because I didn't write them down on a piece of paper like he asked.)

Now here comes the comical part.He allows us to work together on the homework assignments. I've been working has hard and know my stuff at least as well if not better than everyone else in the class. I've spent hours helping 4-5 of my classmates with their codes. In fact I basically let 2 people copy my codes and when they still couldn't get their codes working I just told them to copy the numbers I got. And they both got full points on their assignment.

He also asked us to find the orthogonal projection of sin(x) onto p3[0,1] and cos(x) onto p4[0,1]. Almost everyone in the class just wrote down the formulas without calculating the integral and they all got full credit anyway. While I actually wrote both a mathematical code and MATLAB code to calculate the orthogonal projections.

**In simple words people got full credit by just copying my answers while I got 0's on the exact same problems because I didn't turn in a hard copy. And he actually saw me helping people out and basically giving them my asnwers.( I sat in the front row.)**
