शंकु-परिच्छेद|परवलय |परवलय के मानक समीकरण |OMR

A circle touches the x-axis and also thouches the circle with center (0, 3) and radius 2. The locus of the center of the circle is a circle (b) an ellipse a parabola (d) a hyperbola

परवलय |वृत्त |दीर्घ - वृत्त |आयताकार |त्रिकोणमितीय अनुपात के ग्राफ |OMR|Summary

The locus of the centre of a variable circle touching circle |z|=5 internally and circle |z-4|=1 externally is (A) a parabola (B) a hyperbola (C) an ellipse (D) none of these

With a given point and line as focus and directrix,a series of ellipses are described. The locus of the extremities of their minor axis is an (a)ellipse (b)a parabola (c)a hyperbola (d) none of these

The centres of those circles which touch the circle,x^(2)+y^(2)-8x-8y-4=0 ,externally and also touch the x -axis,lie on (1) a circle.(2) an ellipse which is not a circle. (3) a hyperbola.(4) a parabola.
