Question

Starting with the circle x2+y2=$$r2x^2$$ + $$y^2$$ = $$r^2$$, which algebraic substitution describes stretching the circle horizontally by factor 1"\u003es\u003e1s\u003e1 to form an ellipse?

Accepted Answer

(xs)2+y2=r2(\frac{x}{s}$$)^2$+y^2$$=$$r^2$$

Answer

x2+(ys)2=$$r2x^2$$+(\frac{y}{s}$$)^2$$=$$r^2$$

Answer

(sx)2+y2=$$r2(sx)^2$$ + $$y^2$$ = $$r^2$$

Answer

x2+(sy)2=$$r2x^2$$ + $$(sy)^2$$ = $$r^2$$

Starting with the circle x2+y2=r2x^2 + y^2 = r^2, which algebraic substitution describes stretching the circle horizontally by factor s>1s>1 to form an ellipse?

Starting with the circle $x^{2} + y^{2} = r^{2}$ , which algebraic substitution describes stretching the circle horizontally by factor $s is greater than 1$ to form an ellipse?
