Reading the text:
- Read through the section before the material is covered in class. Even if you don't completely understand the section, at least you know what will be covered.
- After lecture, review your notes, and look back through the section that was covered; if you are still unsure about something, get clarification.
- If something is labeled Theorem, Definition, or has a box around it, it's important.
- Don't skip over the example problems.
- Keep a separate sheet of all the important formulas along with the page numbers so you can refer back to them later if you need to.
- If you plan to continue with math, don't skip over proofs!
- If you come across something you don't understand, make a note and ask the instructor or TA.
Homework:
- Form a study group or exchange emails and/or phone numbers early in the term.
- Give yourself at least a couple of days to do the homework. If you have questions, you'll have plenty of time to email classmates or discuss them during your study session.
Studying for a test and taking exams:
- Definitions are really important; know what they are and how to use them.
- Review homework and/or chapter review problems.
- Look through the examples in the chapters, and know how they arrived at each step. Also, know how, when given a word problem, to set up the equations. In other words, know the applications really well.
On the exam:
- If the formulas aren't given, write the important ones on the top before you look over the test. Formulas are sometimes hard to remember under pressure.
- If you have time at the end, double check your answers, no matter what!
- If you come across something you can't remember, move on; another problem/section of the test might jog your memory.
- Know how to use your calculator! The TI-89, for example, can be used to find derivatives and integrals. This doesn't mean you don't have to show work; it's just a great way to double check your work.
Things to have a firm grasp of:
Limits
- Definition of a limit
- Does a limit exist? ($\lim_{x \to c^+} f(x) = \lim_{x \to c^-} f(x)$; limit as x approaches c from the right is equal to the limit as x approaches c from the left).
- How to evaluate infinite and finite limits (i.e., $\lim_{x \to \infty} f(x)$ and $\lim_{x \to c} f(x)$ where c is a constant)
- Know the special cases (indeterminate forms and L'Hospital's Rule, removable discontinuities, etc.)
- Properties/Laws of limits
Continuity:
- Definition of continuity and discontinuity
- Test for continuity ($\lim_{x \to c^+} f(x) = \lim_{x \to c^-} f(x) = f(c)$ where c is constant)
- Left continuity vs. right continuity
- Continuity on an interval
Derivatives:
- Definition of a derivative
- When you can take a derivative (continuity must exist)
- Derivative of a function using limits ($f'(a) = \lim_{h \to 0} \frac{f(a+h) - f(a)}{h}$)
- Derivative rules: power rule, chain rule, constant multiple rule, difference rule, product/quotient rule, etc.
- Finding maximums and minimums (concavity, second derivatives)
- Derivatives of trig functions
- Implicit differentiation
- Special cases (derivative of e, logs, exponents, etc.)
Applications:
- Rate of change in volume/area/length/etc. are common applications of derivatives
- Optimization problems
- The chapters usually have great application examples; look through them carefully and know how they arrived at each step. The chapter problems are also great practice.
