### proving the elips equation

The general equation of an ellipse is x^2/a^2+y^2/b^2=1, where a and b are the lengths of the semimajor and semiminor axes. The following proof uses the distance property: the sum of the lengths of the lines between any point on the ellipse and its two foci is constant. Both foci lie on the major ax

### prove that C,D,H,E are concyclic

The picture shows the secants from point P. The quadrilateral CDHE is required to be proved to be a cyclic quadrilateral. That means that CDH+CEH=180=DCE+EHD. Join CB and AD, and join AH and BE. From this construction we get two pairs of similar triangles: APD and BPC, and APH and BPE, because

### What is the radius of this vicious circle?

A vicious circle The ends of the diameter of a unit circle are joined to make a smaller circle. The ends of the diameter of this smaller circle are joined to make an even smaller circle. And so on indefinitely. If the radii of all the circles (including the initial unit circle) are l

### Find the point(s) where the line through the origin with slope 6 intersects the unit circle.

The line passes through the origin so its equation is y=6x. The equation of the unit circle is x^2+y^2=1, which has centre (0,0) and radius 1. Substituting y=6x in the equation of the circle we have 37x^2=1 and x=+sqrt(1/37). Therefore the y values for the intersections are y=+6sqrt(1/37). The

### . A car dealership has 556 new cars on its lot.

There seems to be one number missing: the number of black cars with automatic transmission and a sun roof, so we'll call this number X. It's helpful to use a diagram (Venn diagram). Draw a large circle (ellipse or other enclosure) containing three interlocking circles. I'll use the word "circle

### Prove that any chord [AB] of the larger circle is bisected by the smaller circle.

The small circle passes through O and touches the large circle at A, so AO is a radius of the large circle and a diameter of the small circle, since point A is a tangent point to both circles, and N is the intersection of the small circle with the large circle. Angle ANO is a right angle,
