The equation of a curve, the functions of two variables, and the concept of an equation of a curve are explained by the use of examples and problems. The parabola is defined as the locus of a point which moves so that it is always the same distance from a fixed point called the focus and a given line called the directrix. In the x,y coordinate system we normally write the xaxis horizontally, with positive numbers to the right of the origin, and the yaxis vertically, with positive numbers above.
