A graph is defined in polarco-ordinates as `r(theta)=cos theta + 1/2`. The smallest x-coordinates of any point on thegraph is

Describe the graph of r=(3)/(cos theta)

Express the polar equation r=2cos theta in rectangular coordinates.

The locus of the point whose co-ordinates are x = 3 cos theta + 2 , y = 3 sin theta - 4 , where theta is a parameter , is

The centre of the circle r^(2) - 4r (cos theta + sin theta) - 4 = 0 in cartesian coordinates is

Transform to Cartesian coordinates the equations: r^(2)=a^(2)cos2 theta

If by shifting the origin at (1,1) the coordinates of a point P become (cos theta, cos phi) then the original coordinates of P were
