Part 1 book “Advanced engineering mathematics” has contents: First-order ODEs, second-order linear ODEs, higher order linear ODEs, systems of ODEs, phase plane, qualitative methods, series solutions of ODEs, special functions, laplace transforms, linear algebra - matrix eigenvalue problems, and other contents. | 11/4/10 12:05 PM Page 2 Systems of Units. Some Important Conversion Factors The most important systems of units are shown in the table below. The mks system is also known as the International System of Units (abbreviated SI), and the abbreviations sec (instead of s), gm (instead of g), and nt (instead of N) are also used.
