Logarithmic Functions
摘要
In this chapter, we will discuss the laws of logarithms, the techniques for solving logarithmic equations, sketching logarithmic functions, and applications. Logarithmic functions are derived from exponential functions by finding inverses thus a linkage between exponential and logarithmic functions will be emphasized. The methods of sketching logarithmic functions using short- and long-run behaviors, including limits to justify these behaviors, will parallel with general techniques applied in prior chapters. Monotonicity and concavity of logarithmic functions will also be discussed and reasoning with logarithmic functions will conclude this chapter.
