After studying mechanical vibration and resonance caused by a sinusoidal forcing function, it would be nice to also teach the students how to work with other periodic forcing functions - e.g. square waves & sawtooth waves - and Laplace Transforms are, to my knowledge, the best way to deal with these.12 years ago At 4:29 of the video Sal begins integration. He starts with -1/s times e to the -st but it gets hairy for me because what happened to adding 1 to the exponent?? • ( 14 votes) Flag Ashish Rai 11 years ago It involves integration by substitution, wherein: Let -st=u => du = -s.dt Thus int e^-st = int (-1/s) e^u du = -1/s e^uThe κ-Laplace transform proposed in this note is just one form of modified Laplace transformations. So far, regarding their mathematical properties [11, 12] and application [for transforms of various functions see, e.g., 13], the literature makes use of the q-modified versions of Laplace transforms, first proposed long ago by Hahn .Instagram:https://instagram. kansas football play by playgreek women's basketballbill self basketballencanto etsy Laplace Transform helps to simplify problems that involve Differential Equations into algebraic equations. As the name suggests, it transforms the time-domain function f (t) into Laplace domain function F (s). Using the above function one can generate a Laplace Transform of any expression.
