[color=#000000]The following applet illustrates a hyperboloid of 2 sheets. The equation of this particular hyperbola is [/color][math]\frac{x^2}{a^2}-\frac{y^2}{b^2}-\frac{z^2}{b^2}=1[/math][color=#000000]. [br][/color][br][b]Note: This applet will only work if the[/b] [b][color=#1e84cc]blue point[/color][/b] [b]is on the sheet containing V_2.[/b] [br][br]V_1, V_2 = vertices[br]F_1, F_2 = foci[br][br]How does the action you see here compare with the action seen [url=https://www.geogebra.org/m/u3Gay8Dp]here[/url]?
