Re: y=Inx okay so i get that when x= 1, ln(x) crosses the x axis Therefore ln(1) = 0 right? Therefore ln(1+d) = d - for d small enough (since the function slowly increases from zero as x increases from 1) so that's my understanding of the question, etc? but from that i don't get how do find...

Re: y=Inx i actually have no idea what you are trying to ask me?

Re: y=Inx nupe?? is the slope just 1 ? how do i know two points on the line?

guys I need loads of help for this question(s)? what do i even do ?!? Sketch the curve y = lnx and find the tangent line to this curve at the point where the curve crosses the x-axis. Deduce that, for small delta, ln(1 + δ) ≈ δ . - I know what the y = Inx curve looks like but what do i do...

okay so i was able to do the first part! however still have no idea how to go about doing the second half??!

hey guys! I'm really confused as to what this question is trying to ask me! can someone help me out :) Air pressure decays approximately exponentially at about 0.4 per cent for each rise of 30 metres above sea level. If we let p = p(h) denote air pressure (measured in some appropriate units) at...
