How fast does an Exponential function increase? Let the unit length be 1cm on the X- and Y- axes. T

The discovery of Nepture (Roman God of the sea) should be attributed to Mathematics. The orbit of Uranus (God of the sky) is apparently different from that computed by mathematics, making people conjecture that there be another planet.
