Remember that the base is 10 and we are considering natural logarithms or logs only. As mentioned earlier, the mantissa has to be read from a standard log table. Log tables consist of rows that go from 10,11, up to The columns have values 0,1, 2, up to 9. Beyond the 10 columns, there is another column which is known as the mean difference. For determining the mantissa, a particular row has to be read off and the mean difference has to be added from the table. For mantissa, read from the table a number From the rows, choose 50, and read off from the number under the column 0.

The number given in the log tables is Now read, in the same row, the mean difference under 2.

This number is given as 2. From the rows, choose 72, and read off from the number under the column 9.

A Complete Table Of Common Logarithm And Antilogarithm For Mathematics Students

Now read, in the same row, the mean difference under 8. This number is given as 5. From the rows, choose 98, and read off from the number under the column 8. Now read, in the same row, the mean difference under 7. This number is given as 3. Thus log 0. From the rows, choose 12, and read off from the number under the column 3. Now read, in the same row, the mean difference under 4. This number is given as The log of will be as follows : this is a five digit number, so the last that is the fifth digit will have to be rounded off.

Finding the Inverse of the Sine Function

The fifth digit is 4, which is less than 5. So take the last digit is 0. Thus the mantissa of will be same as the mantissa for The log of will be as follows : the last digit 6 is rounded off as 1 and is added to the second last number 4.

Antilog table for base 10 is readily available.

A Nature Research Journal. WHAT Napier actually gives in his table is a series of natural sines with a corresponding series of logarithms which diminish as the sines increase. If a Napierian logarithm is considered to be the logarithm of the sine opposite to which it stands, the base is approximately e 1 ; but we may, if we like, regard the logarithms as logarithms of cosecants, and the base is then approximately e.

The classroom has not been Sales prospecting refer to the process of looking for potential clients, customers, or buyers to develop new businessTHE following treatise constitutes the third volume of a course of Mathematics designed for colleges and high schools, and is prepared upon substantially the same model as the works on Algebra and Geometry.

It does not profess to embody every thing which is known on the subject of Trigonometry, but it contains those principles which are most important on account of their applications, or their connection with other parts of a course of mathematical study.

The aim has been to render every principle intelligible, not by the repetition of superfluous words, but by the use of precise and appropriate language.

Whenever it could conveniently be done, the most important principles have been reduced to the form of theorems or rules, which are distinguished by the use of italic letters, and are designed to be committed to memory. The most important instruments used in Surveying are fully described, and are illustrated by drawings. The computations are all made by the aid of natural numbers, or with logarithms to six places; and by means of the accompanying tables, such computations can be performed with great facility and precision This volume, having been used by several successive classes, has been subjected to the severest scrutiny, and the present edition embodies all the alterations which have been suggested by experience in the recitation room.

BOOK I. Nature of Logarithms Areas of Figures bounded by Right Lines Par Explanation of the Vernier Right-angled Spherical Triangles Logarithms are numbers designed to diminish the labor of Multiplication and Division, by substituting in their stead Addition and Subtraction. All numbers are regarded as powers of some one number, which is called the base of the system; and the exponent of that power of the base which is equal to a given number, is called the logarithm of that number.

The base of the common system of logarithms called, from their inventor, Briggs' logarithms is the number Hence all numbers are to be regarded as powers of The logarithm of every num.

The logarithm of every number between and is some number between 2 and 3, i. The preceding principles may be extended to fractions by means of negative exponents.

Hence it appears that the logarithm of every number between 1 and 0. The logarithms of most numbers, therefore, consist of an integer and a fraction. The integral part is called the characteristic, and may be known from the following RULE.

The characteristic of the logarithm of any number greate7 than unity, is one less than the number of integral figures in the given number.
