    Rearranging Equations: Making a Variable the Subject

    If you were to isolate C/D as you did in your first step, then A should have been the numerator of the right side. While isolating, technically you divide both sides by the same expression (in this case B x E x F to eliminate them from the side where C/D is). A simpler method would be to...

    What is the Limit of (x + 1)ln x as x Approaches 0?

    Ah. My mistake. You said "numerator". I hadn't realized that once you'd found the limit of either numerator or denominator you could go to work on each separately (I thought if you used L'Hopital you always had to differentiate both haha). Anyway, after a couple more differentiations of...

    What is the Limit of (x + 1)ln x as x Approaches 0?

    Thank you for replying. I did that, and I got: - 2 ln x - (ln x)2, which is inf - inf. I'm rather confused how to convert that to numerator/denominator form again, though.

    What is the Limit of (x + 1)ln x as x Approaches 0?

    Homework Statement lim as x approaches 0 of (x + 1)ln x Homework Equations The Attempt at a Solution I tried using ln y = (ln x)[ln (x + 1)] then: ln (x + 1) ---------- 1 --- ln x to make it eligible for L'Hopital's Rule. Then differentiating the numerator and the denominator, I got: 1 --- x...
