    A Definite integral where solution. involves infinity - infinity

    oops! {x^(1/2){1+1/x}^(1/2)} / x ^(1/2){1+1/(x^2)}^(1/4) . i got this in the notebook, forgot to use paranthesis and forgot to edit the second term that i copy pasted from the first.

    A Definite integral where solution. involves infinity - infinity

    Correct me if i am wrong. ln [x^(1/2) { 1+ 1/ x^(1/2) } / x^(1/2) { 1+ 1/ x^(1/2) }] I would get ln 1. which is equal to zero and hence the required answer. Thanks a lot Mark 44 and Dick.

    A Definite integral where solution. involves infinity - infinity

    Thank you very much Mark44 and Dick. I got the same integral as Mark44. I understand what Dick is saying but I'm not allowed to use L hospital's rule at school. I can't figure out any other way. Is there an alternate way to evaluate the above integral?

    Length of Curve with Parametric Equations x=cost and y=sint in the xy-plane

    Hint: (Zcos t, Zsin t) where Z is a some arbitrary constant(in the set +R) represents a circle. In your case, substitute Z=1, 0<t<pi.

    Finding the Minimum Hypotenuse of a Right Angled Triangle | Hypotenuse Homework

    Yes you're right. I went to school today and got the question sorted out, it wasn't isosceles. A friend of mine verbally stated out the question he had picked up from some guide book, and I seem to have taken it down wrongly, mixed up multiple questions! Sorry about that. I panicked as I had...

    Finding the Minimum Hypotenuse of a Right Angled Triangle | Hypotenuse Homework

    Hi! Thanks for your time. I was not referring to theta as angle BAC or BCA, which is pi/4. For a point X, a and b are fixed, and are related (except that I am unable to figure it out straight). If I can represent h as an equation of a alone, or b alone, or some other variable theta on which a...
