What is co-ordination number ?

Find the Cartesian co-ordinates of point whose polar co-ordinates are (4, (pi)/(3)) .

Which of the following co-ordinates muscular activity?

Number of points with integral co-ordinates that lie inside a triangle whose co-ordinates are (0, 0), (0, 21) and (21,0).

Number of points with integral co-ordinates that lie inside a triangle whose co-ordinates are (0, 0), (0, 21) and (21,0).

he co-ordinates of the centroid of a triangle PQR are (2, -5). If Q = (-6, 5) and R = (11, 8), calculate the co-ordinates of vertex P.

A point P is such that the sum of the squares of its distances from the two axes of co-ordinates is equal to the square of its distance from the line x-y=1 . Find the equation of the locus of P.

Which of the following quantities are independent of the choice of orientation of the co-ordinate axes?
