Sketch the dependence of l versus h on cartesian axes.

The distance l from a point at a height h above the Earth's surface to the horizon can be approximated using Pythagoras theorem by the expression: l = h * SQRT(1 + (2*re/h)) , where re is the radius of the Earth. (a) Sketch the dependence of l versus h on Cartesian axes. (b) Thus determine approximations for l by taking l
