What you'll learn
- Identify an equation as an ellipse from the fact that both squared terms have the same sign and unequal coefficients
- Read the center off (x - h)^2/a^2 + (y - k)^2/b^2 = 1, handling the sign inversion
- Determine the two distances from the center to the curve by taking the square roots of the denominators, and state which direction each measures along
- State whether an ellipse is wider than tall or taller than wide by comparing the two denominators
- Recognize the circle as the special case in which the two denominators are equal, and explain why
- Convert an ellipse equation to standard form by dividing through so the right side is 1
