    Simple Region Question for a Double Integral Substitution

    Homework Statement Evaluate the double integral integral ∫∫2x^2-xy-y^2 dxdy for the region R in the first quadrant bounded by the lines y=-2x+4, y=-2x+7, y=x-2, and y=x+1 using the transformation x=1/3(u+v), y=1/3(-2u+v).Homework Equations The Attempt at a Solution I've obtained the Jacobian...

    Undergrad Help Finding The Tension Force of a String (Not a Homework Problem)

    I'm trying to put together a little physics project, and I've constructed a rudimentary stringed instrument using a 2-liter bottle and some string. The string is fed through the bottom of the bottle and wound around a small dowel at the top end, and a small hole has been cut near middle of the...

    Limit ln(n-1/n+1) as n->infinity

    Yes ln[(x-1)/(x+1)] is what I actually meant, thanks for correcting my mistake.

    Limit ln(n-1/n+1) as n->infinity

    Thank you! After getting your response I looked further into the problem with the hp and figured it out. I had a 1. instead of 1 (sans decimal), and it won't take a limit with the decimal because it's a "real" number. This was of much help.

    Limit ln(n-1/n+1) as n->infinity

    Homework Statement Hi! I need help confirming the limit of ln(n-1/n+1) as n->infinity. If you multiply top and bottom of the quotient by 1/n you'd end up with ln(1) = 0, no? I must be missing something rather simple here because my hp50 won't even compute. Thanks! Homework Statement
