What is a natural logarithm? Why is ln(1) = 0?
In: Mathematics
Lets use another equation:
e^0=1
Well you might know that already as everynumber to the power of 0 =1. we pretend we don’t.
e = eulers number is a special number like Pi for example. it has an opposite just like multiplication is the opposite of divison.
This opposite is ln. the logarithm naturalis.
using it on the equation gets us
ln(e^0)=ln(1)
ln and e cancel eachother out and the zero moves down. so we get:
ln(1)=0
