The inverse of the logarithmic operation is exponentiation. The logarithm is commonly used in many fields: that with base 2 in computer science, that with base e in pure mathematics, and that with base 10 in natural science and engineering. The logarithm of a product is the sum of the logarithms of the factors. Logarithmic Functions Free to share, print, make copies and changes.

Logarithms with base equal to 10 are called common logarithms. They are most applicable in physical and natural sciences and engineering. Logarithms with base equal to e are called natural logarithms. They are most applicable in pure mathematics. Logarithms with base equal to 2 are called binary logarithms.

The logarithmic and exponential operations are inverses. If given an exponential equation, one can take the natural logarithm to isolate the variables of interest, and vice versa.

The natural logarithm is the logarithm with base equal to e. Also known as Euler's number, e is an irrational number that often appears in natural relationships in pure math and science. The number e and the natural logarithm have many applications in calculus, number theory, differential equations, complex numbers, compound interest, and more.

If a logarithm and/or its base are not whole numbers, evaluation can be near- impossible. One can change the base of a logarithm by expressing it as the quotient of two logarithms with a common, same base. Changing a logarithm's base to 10 makes it much simpler to evaluate; it can be done on a calculator. Changing Logarithmic Bases Free to share, print, make copies and changes.

The logarithmic graph is similar in shape to the square root graph, but with a vertical asymptote as x approaches 0 from the right. With use of defined numbers, logarithmic graphs can be shifted horizontally and/or vertically. When graphing logarithms, it is usually advisable to use several x values between the vertical asymptote and the next integer. After the first integer, it is usually best to make points less and less frequently. Graphs of Logarithmic Functions Free to share, print, make copies and changes.

Logarithmic graphs use logarithmic scales, in which the values differ exponentially. For example, instead of including marks at 0, 1, 2, and 3, a logarithmic scale may include marks at 0.1, 1, 10, and 100, each an equal distance from the previous and next. Logarithmic graphs allow one to plot a very large range of data without losing the shape of the graph. Logarithmic graphs make it easier to interpolate in areas that may be difficult to read on linear axes. For example, if the plot of y=x5 is scaled to show a very wide range of y values, the curvature near the origin may be indistinguishable on linear axes. It is much clearer on logarithmic axes.

Interactive Graph: Graph of Binary Logarithm Graph of binary logarithm with the equation. The function's slope decreases with increasing x, thus containing its vertical growth. More importantly, the scale is greatly reduced, allowing for easy visualization of large values of y. In many cases, by taking the logarithms of exponential equations, the equations become linear, and plotting the appropriate logarithms can help solve for roots, slopes, and intercepts.
