What is the Type and Orientation of Conics in Problems a and b?

Click For Summary
SUMMARY

The discussion focuses on identifying the type and orientation of conic sections from two specific equations. Problem (a) represents a horizontally oriented ellipse, as indicated by the negative sign in the equation and the denominators of 9 and 1. Problem (b) describes a vertically oriented ellipse, confirmed by the positive sign and the denominators of 25 and 4. Understanding these characteristics allows for accurate classification of conics in future problems.

PREREQUISITES
  • Understanding of conic sections, specifically ellipses and hyperbolas.
  • Familiarity with the standard forms of conic equations.
  • Knowledge of how to determine orientation based on equation structure.
  • Basic algebra skills for manipulating and interpreting equations.
NEXT STEPS
  • Study the standard forms of conic sections, including ellipses and hyperbolas.
  • Learn how to derive the orientation of conics from their equations.
  • Practice identifying conic types using various examples and problems.
  • Explore the applications of conic sections in real-world scenarios.
USEFUL FOR

Students studying conic sections in algebra or precalculus, educators teaching geometry, and anyone looking to enhance their understanding of conic orientations and classifications.

Homework Statement



There are 2 problems a and b.
I've solved for both already.
I just need to know how to describe them by type and orientation.
In other words, what does what I got tell me in regards to type and orientation and how do I know this for future problems? (e.g. hyperbola or ellipse oriented vertically or horizontally)

a) (x-3)^2 (y-1)^2
-------- - -------- = 1
9 1

b) (x+1)^2 (y-1)^2
-------- + -------- = 1
25 4

i see this didnt post right.
the 1 should be under the 2nd fraction in a)
the 4 should be under the 2nd fraction in b)
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
