Derivative Problem

  • #1

The Attempt at a Solution



I took the derivative first and got dy/dx = 2 - 1/x. I then substituted and got the answer 1. I'm confused if I was supposed to use dy/dt at all during this problem, and I don't know if I took the right steps.

Please tell us what the problem is! What did you differentiate to get dy/dx? This makes no sense at all.

i suppose this should be differentiate with respect to x if not there would still be variables of t in your equation of first derivative.
