Mathematics of Engineering - ME17 Final Exam Review, Spring 2008 Note: boxed formulas are so important that you should have them memorized, and should have a good idea how they can be derived or verified Matlab assigning a matrix; view element, row, column of matrix in Matlab + - * .* / ./ ^ .^ ’ plot, semilogx, semilogy, loglog, subplot, title, xlabel, ylabel trig functions, abs, sqrt, exp, log, log10 max, min, sum, cumsum, prod, cumprod logical statements in Matlab: if statement, ~ & | == functions: external, inline, anonymous loops: for, while you will need to write a short Matlab program on the exam! probability basic definitions, rules for mutually exclusive events and independent events probability distribution functions expected values matrices matrix addition, subtraction, multiplication calculate determinant, trace, eigenvalues/eigenvectors, transpose of matrix determinant = product of eigenvalues, trace = sum of eigenvalues inverse of matrix, including “trick” for 2 × 2 matrices: a b c d - 1 = 1 ad - bc d - b - c a calculate norms of matrix - don’t need to memorize formulas, but should know how to use LU decomposition proofs using indices, for example ( AB ) C = A ( BC ) trace( AB ) = trace( BA ) , ( AB ) T = B T A T

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
