IJustWanaPass Report post Posted October 21, 2017 Anyone mind helping me solve this integral? I literally have no clue where to begin. Reply Share this post Link to post Share on other sites
kw0573 Report post Posted October 22, 2017 I think this is for an IA, so I won't go into too much details. If you know all the constants (and ω > 0) then this should be just integration by parts twice. It gets tricky if you have to plug in boundary conditions or initial conditions (ie from solving a differential equation) but likely you can just do that after. When I encountered something similar we had an infinite series instead of an indefinite integral but that trick will not work here. Basically for an infinite series you have to use some integral that equals to the Kronecker delta, such as 1 Reply Share this post Link to post Share on other sites
IJustWanaPass Report post Posted October 22, 2017 I figured it would be better to integrate the equation first and then substitute the values. Anyway, will try both ways, thanks. Reply Share this post Link to post Share on other sites
