上課內容摘要
Week 1
1. The definition of a function. f:X-->Y is called a function if f(x) is uniquely determined. X is called the domain of the definition and Y is called the range.
2. Introduce some basic types of functions.
3. Define the inverse of a function. Let f: X--> range(f) be one-to-one. Then there exists a unique function, f^{-1}: range(f)-->X, such that f^{-1}(f(x))=x for all x in X
and f(f^{-1}(y))=y for all y in range(f). f^{-1} is called the inverse of f.
4. Define the limit of a function.
5. If a function f:X-->Y is not one-to-one or onto, one may be able to modify (shrink) the domain X or the range Y such that on smaller X or Y, the function f is one-to-one and onto. With such modification, we find define the inverse of f. Read what we did for sinx and tanx.
Week 2
1. Homework #1 (due 9/29): p.100:54,57;p.114:78;p.134:60;p.142-143:1,6,15,31,32;p.145-146:14,17,25,27.
2. Precise definitions of limits. Finding the relation between δ and ε is the key to prove the existence of the limit.
3. Define a continuous function. A function f:(a,b)--> R and c in (a,b) is said to be continuous at c iff lim_{x→c}f(x)=f(c). The continuity at the endpoint is defined similarly with the one-sided limit.
4. The composite of two continuous functions is continuous.
5. Definition of removable discontinuities.
6. A continuous function possesses the intermediate value property, i.e., if c is between f(a) and f(b), then there exists a x in (a,b) such that f(x)=c.
7. Using the intermediate value property to find roots of a continuous function.
Week 3
1. We gave the definition of differentiability. Define f'(x_0)=lim_{x→x_0}[f(x)-f(x_0)]/[x-x_0] provided the limit exists. We can also define one-sided derivatives (similar to one-sided continuity).
2. Differentiability implies continuity, but not the other way around.
3. Derivatives of some elementary functions.
4. Differentiation rules, e.g., product and quotient rules.
5. The chain rule (important): derivative of a composite function.
6. Implicit differentiation (good trick). For example, we can find the equation of the tangent line at a point of a given curve without knowing the explicit form of the function.
