    Graduate Whats the point of a function being orthogonal?

    Well I did post this in the maths section. Could you elaborate particularly what the point of orthogonality of Fourier series and Sturm-Liouville problems implies?

    Graduate Whats the point of a function being orthogonal?

    I understand that a function is orthogonal if the inner product of any two functions of an infinite series equal to zero. My question is why do we prove functions are orthogonal? What can we do with this information?

    How Do You Integrate (x^(1/2))/ln(x) Using Integration by Parts?

    I tried it this way. The furthest I got was (2*(x)^(1/2))/lnx - Integral of (2/((x)^(1/2))(lnx)^2 dx Still not able to attain the answer.

    How Do You Integrate (x^(1/2))/ln(x) Using Integration by Parts?

    QUESTION: The question is to find the improper integral of (x^1/2)/lnx dx. MY ATTEMPT: 1)I tried it byparts, by taking 1/ln x as 'u' or the first function but i got stuck. 2)Alternatively, I tried substituting x=e^2t in hopes to eliminate ln for a simpler byparts integration, but that didn't...
