¿what'syourbeef? Posted February 12, 2007 Share Posted February 12, 2007 The harmonic oscillator can be thought like a spring in SHM. Net energy for a particle in SHM is given by: frac {kA^2}{2} Kinetic energy at any time t is : frac {kx^2}{2} Potential energy at t is: frac {k(A^2 - x^2)}{2} The two relations can be easily thought of as PE +KE = total energy.

dutchsoccerfan Posted February 12, 2007 Share Posted February 12, 2007 ya im pretty sure all that is right is that TE=pe+ke. The hard part is to integrate it and derive the final answers which are KE=3E/4 and PE=E/4 Link to comment Share on other sites More sharing options...

dutchsoccerfan Posted February 12, 2007 Share Posted February 12, 2007 you make the y coordiante a squared. so the two points you use are (a,a squared) and (1+a,1+a sqaured) use slope formula to solve, and you get 2a+1 Link to comment Share on other sites More sharing options...
kazin! Posted February 12, 2007 Share Posted February 12, 2007 I didn't really understand that, but I'll figure it out in a sec. While I was looking at the answers I saw that i screwed up this question. Find the equation of the tangent line to the graph of the given function at the given point. g(x) = 2x + 1 / x - 1 (2,5) Link to comment Share on other sites More sharing options...
