Calculus Differentiation dy/dx = y y = ex eix = cosx + i sinx Calculus Differentiation dy/dx = y y = ex eix = cosx + i sinx Calculus Differentiation dy/dx = y y = ex eix = cosx + i sinx dsinx/dx = cosx and dcosx/dx = - sinx thus d2sinx/dx2 = -sinx physics.hmc.edu Below is the image at: www.irregularwebcomic.net/1420.html at: zaksiddons.wordpress.com/.../ Problem 3 Plot on graph paper the function y = sinx from x = 0 to x = 360o y 0 x -y 0 15 30 45 60 75 900 ……………… 3600 x Faraday’s Coil How much doubt about that? Maxwell's Equations Maxwell's equations represent one of the most elegant and concise ways to state the fundamentals of electricity and magnetism. From them one can develop most of the working relationships in the field. Because of their concise statement, they embody a high level of mathematical sophistication and are therefore not generally introduced in an introductory treatment of the subject, except perhaps as summary relationships. These basic equations of electricity and magnetism can be used as a starting point for advanced courses, but are usually first encountered as unifying equations after the study of electrical and magnetic phenomena.
