    Series Convergence: An=Ʃ(k)/[(n^2)+k] - Find Value

    actaully i don't want to find the limit of the fn. i want the sum of the series.

    Series Convergence: An=Ʃ(k)/[(n^2)+k] - Find Value

    Homework Statement An=Ʃ(k)/[(n^2)+k] the sum is k=0 to n, the question is, to which value does the this series converge to Homework Equations i know for sure that this series converges, but could not figure out the value to whch it converges The Attempt at a Solution i did the...

    How Does Viscosity Affect Flow Rate According to the Hagen-Poiseuille Equation?

    Homework Statement see the pic attached Homework Equations Newton's law of viscosity The Attempt at a Solution okay, i knew that , since the viscosity of the fuid in the second tube is low, it flows easily than the other, but i don't know which exact euation connects visocsity...

    Interesting problem i came acrosss

    i'm not this dumb usually, its just that i got stuck here. thanks a lot.

    Interesting problem i came acrosss

    oh wait, i got it, x mustt be zero, so that for diff values of a and b, they get you the same y value. i got it now.

    Interesting problem i came acrosss

    beacuse, at the same x point, a and b has to be equal to get you to the same y value as the equation suggests

    you tell me, is there something wrong with this problem?

    Interesting problem i came acrosss

    a small addendum, what i actually mean by angle b/w curves is the angle b/w their tangents at that point.

    Interesting problem i came acrosss

    okay, there are two curves: curve1: y=a^x and curve2: b^x. what is the angle between them at their point of intersection. given that (a≠b). My general method: if i wanted angle b/w the curves y=x^2 and y=(x-2)^2, i would easily do it. let A be angle b/w them...

    Any integrating genius? integrate this

    dear jorisL, I'm not aware of gaussian integral. i'll definitely check it out. but, pls tell me, how did you come to conclusion that it can be solved by gaussian integral. when DH suggested e^-z^2 . i thoght it just meant i...

    Any integrating genius? integrate this

    i think u are wrong, this doesn't solve the problem. the problem really lies in applying the limits in the end, not in the substitution.

    Thermodynamics Closed System Energy Balance

    i worked out the problem, and realized that i needed K(spring const) and cross section area of the piston to solve this problem. i think everything worked out is correct. the question says everyhting is in equilibrium at the end which means...

    Any integrating genius? integrate this

    this may seem simple, but try doing this yourself. I've tried sustituting t=e^x , e^-x. but the problem lies after that. do it and see it for yourself.
