										x^2+y^2=x

O(0,0) lies on the circle.


general form of any point on this circle is given by (-g+r(cosØ),-f+r(sinØ)) hence here it is P(1+1(cosØ),1(sinØ)).


thus for mid pt. of chord OP:


x= (0+1+1cosØ)/2 =>(1+cosØ)/2    (1)


y=sinØ/2;     (2)


from (1) and (2), (cosØ)^2= (2x-1)^2,   (3)


                          (sinØ)^2=(2y)^2;     (4)


adding (3) and (4)


     sqr(2x-1)+sqr(2y)=1,


 or x^2 +y^2-x=0 ,which is the required eq.

What is the area of the triangle formed by the the asymptote of a hyperbola and any tangent to the hyperbola
 
 
Dear Student, Hint: Find the two points of intersections of tangents with the asymptotes to get the two vertexes. And third vertex is the centre of hyperbola. Now Use these three pints to...

if | z – 4 | + | z – [12/5] | = 10 represents an ellipse , then what is its eccentricity?
 
 
I am assuming that [12/5] is the greatest integer function, which will change the equation to |z-4| + |z-2| = 10 Now Interpreting this as an ellipse is simple, basically the equation can be...

shortest distance between the skew lines r=(i+2j+3k)+t(i+3j+2k) and r=(4i+5j+6k)+(2i+3j+k) is?
 
 
for shortest distance between skew lines we use a formula d=(a2-a1).(b1*b2)/mod(b1*b2) where a1 and a2 are points from which the given two lines are passing b1 and b2 are direction ratios...
