Could someone please explain to me what occurs when things are halved.

**drwls**, Friday, May 15, 2009 at 12:54ame^x becomes e^(x/2) is x is halved

ln x becomes ln(x/2) is x is halved.

Start out with x = 4 and compare what you get with x = 2 and x = 1.

ln4 = 1.386

ln2 = 0.693

ln1 = 0

Each time x doubles, ln x increases by 0.693

e^4 = 54.60

e^2 = 7.389

e^1 = e = 2.718

Each time x doubles, e^x gets squared.
