	A rectangular hyperbola		2013-09-19
		Soumya pose la question : Is the graph of an inverse variation a RECTANGULAR HYPERBOLA? If it is, then how can be the equation of a rectangular hyperbola be xy=constant , whereas in the books it is written that the graph of a rectangular hyperbola is- x^2-y^2=a^2? Chris Fisher lui répond.
	A rectangular hyperbola		2007-11-06
		Gareth pose la question : 2. Consider the rectangular hyperbola xy = c2 with parametrization (x, y) = (ct, c/t), and t 6= 0. i. Derive (i.e. do not just quote) the equations of the tangent and normal at the point P with (parametric) coordinates (cp, c/p). ii. Consider the points P : (cp, c/p) and Q : (cq, c/q) on the hyperbola. Find the equation of the straight line that joins the points P and Q. iii. Consider a point R : (cr, c/r) also on the hyperbola, and suppose that in the triangle PRQ, \PRQ = 90◦. Prove that the normal (to the hyperbola) at R is parallel to the line PQ.

	Sketch the graph of the hyperbola and its asymptotes		2007-03-13
		Katrina pose la question : Given (y-2) ^2 – x^2/4 =1 do the following: Sketch the graph of the hyperbola and its asymptotes. Label the vertices on the graph I attached the graph thanks for your help! Penny Nom lui répond.
	Conic sections		2006-11-19
		Joyce pose la question : My son has a project on conic sections. I need the following information on Parabola, Circle, ellipse,and hyperbola. He can't find the following information for each conic section: equations with explanations, four uses for each shape and Shape explanation. Penny Nom lui répond.
	Some applications of conic sections		2006-11-13
		Burt pose la question : how are circles, ellipses, and hyperbolas used in everyday life Penny Nom lui répond.
	Find the xy equation of the curve on which Brian is located.		2006-02-20
		Skye pose la question : Andrew, located at (0, -2200) fired a rifle. The sound echoed off a cliff at (0,2200) to Brian, located at point (x,y). Brian heard the echo 6 seconds after he heard the original shot. Find the xy equation of the curve on which Brian is located. Assume the distances are in feet and that sound travels at 1100 feet/second. (hint: find the equation of the hyperbola) Stephen La Rocque lui répond.
	A conic		2004-08-10
		A student pose la question : My question is about this equation 32x*2 -18y*2 -64x +72y +248 =0 explain why as x goes to the infinity the graph of the conic looks like y= (3/4)X. What I did to try to find the solution of this problem was to graph and then I thought that maybe trying to find the equation of the asymptotes I could do it, but it was useless -because the equation of the asymptotes is y= +4/3(X-1) -2 and that does not explain why tho conic looks like y=(3/4) x . I would really appreciate your help on this. Penny Nom lui répond.
	A tangent to a hyperbola		2004-08-02
		A student pose la question : The equation of a hyperbola is 32x*2 -18Y*2-64x +72y +248=0. The equation of a tangent line to this hyperbola is y= (16/15)X + 10/3 I have been trying to find the point where this line intersects the graph. What I did was solve for x and then plugged in the result into the equation of the hyperbola, but I am getting two answers and I am supposed to get only one because the line is tangent to the graph. For this reason, I would like to know what I am doing wrong or what I have to do to know which answer is correct. Penny Nom lui répond.
	Uses of conic sections		2003-04-01
		William pose la question : My name is William and I am doing a research paper on conic sections for my 12th grade math class. Part of the project is to find two conic sections in our world today and explain what there purpose is. I really need help in this area because I've been searching the internet for where conic sections are used in our world today and I really can't find anything. If you can tell me specific building or a pyramid that contains conic sections that would be great. Or even something in the universe would be helpful. Leeanne Boehm lui répond.
	A cone in 3 space		2002-03-20
		Matthew pose la question : Let C in R3 be the cone defined by x2 + y2 - z2 = 0 (A) Let P be the plane described by x + 2z = 1 (i) Find a description of P in terms of two parameters s and t . . . Walter Whiteley lui répond.
	A hyperbola centered at (0,0)		2001-12-28
		Carla pose la question : Find the equation of the hyperbola centered at (0,0) with vertices at (0,3) and (0,-3) that is asymptotic to the lines y=+-5x. Find the equation of a hyperbola in standard position foci (1,5) and (1,7) and eccentricity 2. Peny Nom lui répond.
	Circles, ellipses, parabolas and hyperbolas		2001-05-09
		Colleen pose la question : How is an ellipse like a circle? In what way does an ellipse have a center? How is a hyperbola similar and different to an ellipse? How is a parabola similar a different to a circle ellipse and parabola? Pnny Nom lui répond.
	Rectangular hyperbola		1999-12-15
		Aarti Chand pose la question : Why do they call a rectangular hyperbola, rectangular and where the normal hyperbola looks like a rectangle and the rectangular hyperbola looks like a sqaure? Chris Fisher lui répond.
