Sweet Home for Calculus I (Fall, 2008)
同學們，開工了，課程簡介 及教學計畫。
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.
Week 2
1. Homework #1 (due 10/2): p.85, 53, 54, 56; p.93, 34; p.94, 57 ; p.95, 60; p.107, 6, 8; p.109, 73, 82; p.130, 53, 59, 60; p.142, 17. (後面四題較難，需對連續函數充分瞭解）
2. Precise definitions of limits. Finding the relation between δ and ε is the key to prove the existence of the limit. You should work out some examples by yourselves.
4. 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 limit
being replaced by the one-sided limit.
5. The composite of two continuous functions is continuous.
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 began to discuss differentiability. We 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.
3. Derivatives of some elementary functions.
4. Differentiation rules, e.g., product and quotient rules.
5. The chain rule (important) and parametric equations.
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.

2. Derivative of the inverse function. (e^x)'=e^x; (ln |x|)'=1/x.

5. Linear approximation and differentials.
6. Optimization problem. Finding the maximum and minimum of a continuous function on a closed interval [a,b].
7. Let c be in (a,b) and f(c) is a local maximum or minimum, then either f is not differentiable at c or f'(c)=0.
