بسم الله الرحمن الرحيم Coupled Oscillations Zain Yamani Saudi Physical Society Rabi-I, 1433 Agenda for Lecture-2: Up-dates and administrative matters Setting Sun turn red Intro. to Linear Algebra Intro. Lagrangian Mechanics
Up-dates and administrative matters Groups formed Web-site up-date (and modified its URL!!) Interaction-1 posted Please resubmit everything to your TA!! About absences.. When you need to send a “chat” to me (alone)
Sum the sinusoids.. Fourier synthesis
Intro. to Linear Algebra • What is a matrix and why is it important? • Solving algebraic equations with matrices • Rotation by matrices • Coupled Oscillations [T,V]!!!!!!!! • Matrix algebra (adding, multiplying, commuting) • Matrix determinant • Square matrix inversion: • Cofactors • Row reduction • a third way?? guess what?!!
Intro. to Linear Algebra • Eignenvalues and eigenvectors of matrices • Orthonormalization of eigenvectors • The ordered basis set.. • Repeated eignenvalues (degeneracy) • eigenvectors for symmetric matrices (of non-degenerate eigenvectors) • Similarity of matrices • Diagonalization of matrices • Solving differential equations with matrices
Intro. to Linear Algebra A good reference book: An Introduction to Linear Algebra with Applications, by Steven Roman
