Students hoping to advance their studies to include calculus first need to face precalculus in high school or college, which requires not only a basic understanding of algebra, geometry and trigonometry but also knowledge of the TI-84 graphing calculators. This Web guide spotlights the resources students need to prepare and excel in their precalculus classes.
Dulcinea's Insight
- Math and arithmetic Web sites can sometimes be far more helpful than their design suggests. Though not aesthetically pleasing, many of these sites provide valuable observations that can help students and teachers alike.
- Be aware that not all answer and tutorial sites are created equal. Online communities and message boards can be helpful, but remember to double-check the work of those providing answers or ask your teacher for advice.
- There are countless precalculus teaching tutorials that you can download for free or purchase for a small charge. However, not all programs are equal in quality and accessibility, so don’t be afraid to ask your teacher for suggestions.
