Should I get a graphing calculator just to leave it at home?

Click For Summary
SUMMARY

The discussion centers on the necessity of a graphing calculator for students tackling integral and differential calculus, as well as algebra. While some participants advocate for the calculator's utility in visualizing graphs, others emphasize the importance of mastering manual graph sketching for advanced work. A key recommendation is to focus on practice to improve problem-solving speed rather than relying on calculators. Additionally, Wolfram Alpha is suggested as a superior alternative for home use due to its accessibility and power.

PREREQUISITES
  • Understanding of integral and differential calculus
  • Familiarity with algebraic concepts
  • Basic knowledge of graphing techniques
  • Experience with online computational tools like Wolfram Alpha
NEXT STEPS
  • Practice manual graph sketching techniques
  • Explore advanced features of Wolfram Alpha for calculus
  • Research effective study methods for improving problem-solving speed
  • Investigate the role of graphing calculators in engineering courses
USEFUL FOR

Students preparing for mathematics and engineering courses, educators looking for teaching tools, and anyone seeking to enhance their problem-solving skills in calculus and algebra.

In maths in school we are starting to do a lot of problems involving integral and differential calculus as well as general algebra. The problem is while I can see the correct method of going about obtaining a solution it takes me a long time to get there as the integration and stuff takes up time and I'm not getting marks for it!

I'm not allowed to use a graphic calculator in one of my exams, mechanics. So our teacher doesn't like them in her class. Should I get one anyway and use it at home and for the parts I can use it?

The other thing is that I want to do maths next year and do engineering at uni so I would need one then.

Thanks

Obviously they are good for drawing graphs from "formulas", but IMO they are not really much use in more advanced work. You would be better in the long term learning how to sketch the graphs by hand.

If you are getting the right answers but taking too much time to solve the problems, most likely what you need is lots and lots of practice. Think about what parts of the complete solution are taking most of the time, and concentrate on practicing just that part - don't waste time doing the stuff that you are already good at!
