An equation is a condition or a constraint placed on the x and y coordinates.
The linear inequalities or equations or restrictions on the variables of a linear programming problem are called...... The conditions x ≥ 0, y ≥ 0 are called.......
An electric field prevailing in a region depends only on X and Y coordinates according to an equation, →E=bXˆi+YˆjX2+Y2 where b is a constant. Find the flux passing through a sphere of radius r whose center is on the origin of the coordinate system.
