Description
"Logarithms" Exponential function and logarithmic function PPT courseware (the concept of logarithms in the first lesson)
Part One: Learning Objectives
1. Understand the concept of logarithms, master the properties of logarithms, and be able to perform simple logarithmic calculations. (main difficulty)
2. Understand the equivalence relationship between exponential and logarithmic expressions, and be able to convert logarithmic and exponential expressions into each other. (emphasis)
3. Understand the concepts and notation of common logarithms and natural logarithms.
core competencies
Cultivate mathematical operation literacy by using the mutual conversion of exponential and logarithmic expressions and applying the properties of logarithms to solve problems.
Logarithmic PPT, part 2: independent preview to explore new knowledge
A preliminary exploration of new knowledge
1. logarithm
(1) Interconversion of exponential and logarithmic expressions and related concepts:
(2)The range of base a is___________.
2. Common logarithms and natural logarithms
3. Basic properties of logarithms
(1) Negative numbers and zero ____ logarithms.
(2)loga 1=____(a>0, and a≠1).
(3)logaa=____(a>0, and a≠1).
Think: Why do zero and negative numbers not have logarithms?
Tip: According to the definition of logarithm: ax=N (a>0 and a≠1), there is always N>0, so when converted into logarithm x=logaN, there is no case of N≤0.
First try
1. If a2=M (a>0 and a≠1), then there is ()
A. log2M=a
B. logaM=2
C. log22=M
D. log2a=M
2. If log3x=3, then x=()
A. 1
B. 3
C. 9
D. 27
3. In b=loga(5-a), the value range of real number a is ()
A. a>5 or a<0
B. 0
