    Undergrad Is ∫(1/(x²+25))dx² Correctly Evaluated as log(x²+25)?

    Thanks for the replies :smile:. My teacher also did the same substitution process when i asked him about this. These integrations and differentiations are done in with respect to the x-coordinate which is a straight line . I was wondering if we could carry out these operations with respect...

    Undergrad Is ∫(1/(x²+25))dx² Correctly Evaluated as log(x²+25)?

    My friends were discussing about this problem (which they made up themselves). ∫\frac{1}{x^{2}+25}dx^{2} They were substituting x^2 for y (x^{2}=y) and thus the answer would come to be log(y+25) that is log(x^{2}+25) I don't think this is the case , i guess that we would be...

    Graduate Proof of V-E+F=2-2p (Euler's 2nd formula).

    Hi. This post is about general topology and is Euler's second formula . Can you people help me by finding a proof for V-E+F=2-2p. :smile: Where, p=genus of the surface. F=number of regions the surface is partitioned into. V=number of vertices. E=number of arcs. I'm currently reading...

    Derivative of e^(x^x) with respect to x

    Hi Bruce! The other way i used to do it was to take the natural logarithm of both the sides(one side of the equation being y to suppose it as the function) two times in a row and then differentiating them both sides . Is this what you were talking about ? :)

    Derivative of e^(x^x) with respect to x

    \frac{\partial}{\partial x}u^{v}=\frac{\partial}{\partial x}u^{v}.\frac{\partial}{\partial x}u+\frac{\partial}{\partial x}u^{v}.\frac{\partial}{\partial x}v Can i get any reason or possibly a derivation for this ? Hi tiny-tim! I had been writing so your answer came before I questioned...

    Undergrad Can Anti-Gravity Physics Become a Reality?

    (it's just an imagination) Maybe we could surf over the space time fabric.We could pull it up. The depressions are supposed to have created gravity. the pulled up fabric may be antigravity.
