    How to Find Adjoints of Differential Operators?

    Thank you very much! Is my second part correct where I applied the same concept but this time separate the second derivative?

    How to Find Adjoints of Differential Operators?

    I see so I should've included the function as well. So it would be -d(x2f(x))/dx= -2xf(x)-x2df(x)/dx. So what should my operator look like? Is it everything except for the f(x)?

    How to Find Adjoints of Differential Operators?

    So I messed up for the first part: (##(x2d/dx)^\dagger##) = (##(d/dx)^\dagger##)(##(x2)^\dagger##) Then the result would be: (-d/dx)*(x2)= -2x?

    How to Find Adjoints of Differential Operators?

    Yes I believe I figured it out yesterday! ##(AB)^\dagger##=(##B^\dagger##)(##A^\dagger##) But for this d2/dx2, it will be the same result right or should I not be able to use that rule?

    How to Find Adjoints of Differential Operators?

    Homework Statement Find the adjoints for x2d/dx and d2/dx2 Homework Equations I know that (x2)_dagger=x2 and that (d/dx)_dagger=-(d/dx). The Attempt at a Solution I solved x2d/dx by doing the following: (x2)_dagger * (d/dx)_dagger= (x2) * (-d/dx) thus the answer should be...

    What Was Your Biggest Academic Fear?

    Glad it worked out for you! Must have been hard but I think if you really love something its worth all that hard work you went through.

    What Was Your Biggest Academic Fear?

    Glad to hear that man. I would love to pick a path and put all my effort into it but I'm still deciding which path to take. Once I do I'd put a lot of effort into it just as you did.

    What Was Your Biggest Academic Fear?

    I know everyone's had a big fear during their academic careers; mine currently is the fear of which field to take. I'm a current 2nd year physics major at the University of California, Davis and I am having doubts about physics being the right path for me. I do well in both physics and...

    Need some advice on starting a blog

    I've been wanting to start a blog/website to host my interests in physics and astronomy. I don't know how to make a website so I was wondering if you guys know any blog sites that are pretty good for a science oriented person. I was thinking of trying out Google's blogger but if you guys have...

    What are some popular fish species for angling and hunting?

    Firefox. I had ad block on so I couldn't see the video. Hoho I never seen this video of Monty Python! Thanks!

    What are some popular fish species for angling and hunting?

    haha thank god I didn't say a bigger fish... Thank you for the "fresh" welcome. Also is there a reason why I can't see the picture you posted @micromass? It appears to be white.

    What are some popular fish species for angling and hunting?

    Yep I do like fish though I never about my favorite type of fish before. I would have to say its the Blobfish...naw just kidding. I took some time to look up that fish and its exceptionally strange. But my favorite fish would have to be salmon. Why? Cause my mom makes some delicious food with...
