SUMMARY

The total width of the ellipse defined by the equation 7x² + 7(y-6)² = 6 can be determined by first simplifying the equation to the standard form of an ellipse. Dividing through by 7 yields x² + (y-6)² = 6/7, indicating that the semi-major axis (a) is √(6/7). The total width of the ellipse, which is twice the semi-major axis, is therefore 2√(6/7).

PREREQUISITES
  • Understanding of conic sections, specifically ellipses

How do you find the total width of the ellipse given by the equation 7x^2 + 7(y-6)^2 = 6.

Dividing by 7 gives you

x2 + (y-6)2 = 6/7 = a2 for some a

What shape does that really look like?
