NATURAL LOGARITHMS. Unit Overview. In this unit you will evaluate natural exponential and natural logarithmic functions and model exponential growth and decay processes. You will also solve logarithmic and exponential equations by using algebra and graphs.
The following properties are very useful when calculating with the natural logarithm: (i) ln1 = 0 (ii) ln(ab) = lna+ lnb (iii) ln(a b) = lna lnb (iv) lnar = rlna where a and b are positive numbers and r is a rational number. Proof (ii) We show that ln(ax) = lna + lnx for a constant a > 0 and any value of x > 0. The rule follows with x = b.
Step by step guide to solve Natural Logarithms. A natural logarithm is a logarithm that has a special base of the mathematical constant \ (e\), which is an irrational number approximately equal to \ (2.71\). The natural logarithm of \ (x\) is generally written as ln \ (x\), or \ (\log_ {e} {x}\). Natural Logarithms.
Logarithms. The mathematics of logarithms and exponentials occurs naturally in many branches of science. It is very important in solving problems related to growth and decay. The growth and decay may be that of a plant or a population, a crystalline structure or money in the bank.
