Cartesian co – ordinate system in plane – I

RECTANGULAR CO-ORDINATE AXES: Let X’OX and Y’OY be two mutually perpendicular lines through any point O in the plane of the paper. We call the point O, the origin. Now choose a convenient unit of length and starting from the origin as zero, mark off a number scale on the horizontal line X’OX, positive to Read more about Cartesian co – ordinate system in plane – I[…]
