Calculus I

• Try some online practice differentiating, with some step-by-step help.
• Your textbook is associated with a website that has some review stuff. You could start looking here.
• For those of you struggling or rusty with some of the basics (e.g., complex fractions, completing squares, etc.), try a few of these crude online quizzes
• Try this online quiz, "Trig-a-gnosis", for testing your understanding of the values of sines and cosines. No scores are generated, it is just for your own use. (You should also try the following: using graph paper, draw an angle; guess its sine and cosine; measure the values of x, y and r; compute the values of sine and cosine; then use a calculator to check. When your guesses start to get good, you understand what sine and cosine mean.)
• We use interval notation a lot, so you might enjoy some practice simplifying intersections and unions of intervals in the form of an online quiz.
• A homemade online multiple choice quiz regarding straight lines. This is practice to help you visualize lines given their equations in slope-intercept form. (You need to get straight with lines. Straight lines will be a big part of EACH exam and you should have no illusions about that.) Here are some more, similar quizzes:
  • straight lines. This is practice to help you visualize lines given their equations in slope-intercept form.
  • quadratics.
  • power functions (with positive integer powers only).
  • factored cubics .
  • more factored cubics .
  • factored quartics .
• A discussion about graphing factored polynomials.
• A site with some visually based quizzes, from the maths online gallery, recommended by a former student.
• The folks at Wolfram Research have created an online training video, "Hands-on Start to Mathematica", that introduces key features of Mathematica for education. They claim it will get you using Mathematica 7 ("and more importantly, really understanding it") within 20 minutes. Give it a whirl and tell me what you think. You can post your reactions in our "Class Lounge" Moodle forum.

You might want to check the Web for Calculus stuff. There are tons, so it isn't easy to find something that suits you without digging. You could start at the site below, but you'll probably need to look around awhile before finding something you like. (Hey --- no heavy surfing until you've done your homework.)
