    Verify Orthonormality of exp(2πimx/L)/sqrt(L) for Integer m and 0 ≤ x ≤ L

    Please bear with me hahah, I would like to put this all into words to ensure I am understanding the process. So I am finding that the integral of the products of bra(f) and ket(g) (which is the inner product) which is the equation your wrote in the first post correct? Also, due to the complex...

    Verify Orthonormality of exp(2πimx/L)/sqrt(L) for Integer m and 0 ≤ x ≤ L

    Homework Statement The question given to me was: Verify the orthonormality of exp(2πimx/L)/sqrt(L) for m an integer and 0<or= to x <or= L. Homework Equations I really have no idea where to start on this one. I am taking a math refresher course and we are learning about linear vector spaces to...

    Solving for Inverse of a Complex Matrix with Cayley-Hamilton Theorem

    Little bit of a different question but pertains to the same matrices. If i have a eigenvalue of zero can i still use that as a value in my diagonal matrix?

    Solving for Inverse of a Complex Matrix with Cayley-Hamilton Theorem

    Homework Statement I have matrix F=(11,1, -i1,2, i2,1, 12,2) I calculated the characteristic polynomial to be x2-2x The question is to find the inverse of F Homework Equations I am having a hard time trying to get the inverse out of this. I am used to dealing with real matrices so this may be...

    [Linear Algebra] rotational matrices

    You are write that it isn't correct it should be Rθ+φ =Rθ*Rφ THANK YOU!

    What is the purpose of glacial acetic acid in the oxidation of benzhydrol?

    Totally get that this conversion is oxidation. I was wondering why I would put something in the reaction put that would be more likely to undergo a loss of a proton over the alcohol. In another experiment we utilized glacial acetic acid and NaOCl. The purpose of the acid there is to react...

    What is the purpose of glacial acetic acid in the oxidation of benzhydrol?

    In a lab we oxidized benzhydrol to produce benzophenone. We use glacial acetic acid and sodium dichromate dehydrate to oxidize the benzhydrol. Then we set up the first extraction with water and CH2Cl2 and the second with NaHCO3 and CH2Cl2. I am trying to figure out what all of the...

    How do I rank these leaving groups?

    I got that image from http://www.masterorganicchemistry.com/2011/04/12/what-makes-a-good-leaving-group/ So from that graph and using the pka values the order should be b<c<e<a<d. It is very odd to me that a charged halogen is a better leaving group than a zero charged NH3 or H2O. My reasoning...
