Discussion Overview

The discussion centers on whether knowledge of Geometry is necessary before starting Calculus, particularly in the context of a student's educational trajectory and preparation. Participants explore the relevance of Geometry and Trigonometry in relation to Calculus and share personal experiences regarding their math education.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • One participant questions the necessity of knowing Geometry before starting Calculus, suggesting that a basic understanding of Trigonometry is sufficient.
  • Another participant expresses surprise that someone could reach Calculus without taking Geometry, prompting a discussion about the educational path taken.
  • A participant explains their unique situation of progressing through Algebra II while being in a lower-level Algebra course, indicating a preference to start Calculus before completing Geometry.
  • Some participants argue that while Geometry is not strictly required, it provides foundational knowledge that aids in understanding Trigonometry and Calculus concepts.
  • It is noted that Geometry emphasizes proof skills, which could benefit mathematical development, even if not directly required for Calculus.
  • Another point raised is that Geometry students typically learn basic Trigonometry and Cartesian coordinate proofs, which may be useful in later math courses.

Areas of Agreement / Disagreement

Participants express differing views on the necessity of Geometry for Calculus. Some believe it is essential for a comprehensive understanding, while others argue that it can be bypassed without significant detriment.

Contextual Notes

Participants highlight that the relevance of Geometry may depend on individual degree objectives and the specific mathematical concepts encountered in Calculus.

I am currently finishing up algebra II and I was curious to know if I have to know Geometry before I can start calculus. I would learn Trigonometry but not the rest of Geometry. I would eventually go back to learn geometry after I finish calculus I.

Uhh... I guess you don't really have to know any trig besides a basic understanding of sin/cos/tan and really simple identities... But how did you get to calculus without taking a course in geometry?

I was a bought to explain that in my original post but I decided not to, I might as well explain. I have been learning algebra II even though I am in algebra Ia which is half of algebra I (The second half being algebra Ib). I am nearing the end of algebra II (should be done in a bought 3-4 weeks). Next year my sophomore year, I am taking Accelerated Geometry and I would rather start calculus than learn stuff that I will have to learn in a few months anyway. Also can anyone recommend a good calculus I book?
 
What your degree objective is might determine if you really should study Geometry or not study it. The course called Geometry is not really college-level (the plane and space with formal proofs like you learn in high school). You at least must understand basic common Geometry in order to make sense of a few things you find in Trigonometry and first years-worth of Calculus. Also, having studied Geometry as a course would help you, at least some, when you study Trigonometry.

For Calculus 1 and 2, you NEED Algebra 1, Algebra 2, and Trigonometry. You can learn reasonably well even if you skipped Geometry. One good thing about Geometry is that the course places great emphasis on learning to understand and perform proofs; far more than what you do in Algebra 1 or 2 or even in Trigonometry. A Geometry course then is at least very good for your mathematical development.
 
Another interesting set of thoughts: Geometry students will usually learn a little bit of basic Trigonometry and can learn to derive the laws of sine and cosine. Such students also gain rigorous however brief exposure to cartesian coordinate Geometry proofs before they may need to deal with them in Algebra 2 or in Trigonometry or in Calculus.
