2;2

I’m not sure what “2;2” means here. Could you clarify? Here are the main possibilities and quick results:

• Point or vector (2, 2) in 2D:

  • Length (magnitude): sqrt(2^2 + 2^2) = sqrt(8) = 2√2
  • Unit vector: (2, 2) / (2√2) = (1/√2, 1/√2)
  • Angle with the x-axis: arctan(2/2) = 45°
  • If you want a dot product with another vector, or a projection, tell me the other vector.

• Ratio 2:2:

  • It simplifies to 1:1.

• If you meant something else (e.g., a 2x2 matrix, coordinates in a different system, etc.), please specify.

If you share the exact task (e.g., compute distance to another point, find projection, simplify a ratio, etc.), I can tailor the steps right away.
