A PDF document that explains the definition, properties and applications of logarithms. It includes examples of how to calculate and solve logarithmic equations, and how to use a calculator to find logarithms.
Learn what logarithms are and how they relate to indices, and how to use the laws of logarithms to simplify calculations. This web page contains definitions, examples, exercises and video tutorials on logarithms.
Introduction to Logarithms. -A logarithm is the inverse function for an exponent; therefore, we will review exponential functions first. Review of Exponential Functions. -An exponential function has the general form ( ) = , where 0 < -b is called the base and x is called the exponent. < 1, or > 1.
This topic introduces logarithms and exponential equations. Logarithms are used to solve exponential equations, and so are used along with exponential functions when modelling growth and decay. The logarithmic function is an important mathematical function and you will meet it again if you study calculus.
logarithms allow for the simplification of complex problem situations to basic arithmetic operations. In this unit you will examine the definition and inverse relationship with the exponential function, practice the laws of logarithms, solve logarithmic equations, and explore a
Learn the definition, properties and applications of logarithms with examples and exercises. This presentation covers how to convert between exponential and logarithmic forms, how to use the power property and how to solve problems involving logarithms.
Understanding Logarithms Intuitively. Adam A. Smith. Logarithms make a lot of people anxious. A lot of this has to do with the way they're often taught in high school and secondary school: by memorizing all the proper steps, without imparting much deeper meaning. For example, maybe you were once taught to solve problems like this: log7 49 = ?
