    Degree Point Rotation

SUMMARY

The discussion centers on the feasibility of achieving a non-lattice point through a 1-degree rotation of a point on the circumference of a circle defined by the equation x² + y² = 625, with the center at (0,0) and a point at (-7,24). Participants clarify the definition of a lattice point, questioning whether it refers to integer coordinates or rational coordinates. The inquiry specifically seeks to determine if there exists an integer n such that both 25 cos(n) and 25 sin(n) yield integer or rational results.

PREREQUISITES
  • Understanding of circle equations in Cartesian coordinates
  • Knowledge of trigonometric functions, specifically cosine and sine
  • Familiarity with the concept of lattice points in mathematics
  • Basic knowledge of rotation transformations in a coordinate system
NEXT STEPS
  • Research the properties of lattice points in relation to trigonometric functions

  • Study the relationship between angles and coordinates in polar and Cartesian systems
  • Investigate the conditions under which trigonometric outputs yield integer or rational values
USEFUL FOR

Mathematicians, geometry enthusiasts, and students studying trigonometry and coordinate geometry will benefit from this discussion.

Let's say the center of a circle on a graph is (0,0), and the point at the circumference is (-7,24).

Do you think it is possible to find a point that is not on the lattice point using a 1 degree rotation?

^By that I mean if it is possible to do a 1 degree rotation of the point to find a nonlattice point.

I'm afraid I don't understand your question. You have a circle with center at (0, 0) and (-7, 24) is on the circumference (so the equation of the circle is x^2+ y^2= 625). You then ask "is it possible to find a point that is not on the lattice point using a 1 degree rotation?"

What lattice point? What lattice? Do you mean the lattice of points (x, y) where x and y are both integer? Or the lattice of points (x,y) where x and y are both rational? Or some other lattice?
Are you asking "Does there exist an integer n such that both 25 cos(n) and 25 sin(n) are integer (or rational)?
