table of natural logarithms. This table is for integers in the range −1 <n <100 - 1 <n <100. To find the natural logarithm (that is, with base e e, the natural log base) for the desired n n, look for the ten’s place digit (0 in the case of −1 <n <10 - 1 <n <10) in the leftmost column and the one’s place digit in the topmost row.
1. Introduction. In this unit we are going to be looking at logarithms. However, before we can deal with logarithms we need to revise indices. This is because logarithms and indices are closely related, and in order to understand logarithms a good knowledge of indices is required.
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.
The natural logarithm of x, written ln x, is the power of e needed to get x. In other words, ln x = c. means. ec = x. The natural logarithm is sometimes written logx. e . ln x is not defined if x is negative or 0.
