1.  This is a physics program.
It calculates the horizontal distance a projectile travels when it's projected at an angle.
Note: the angle, theta, is represented by the @ symbol.  (unit: degrees)
        velocity is in meters per second and distance is in meters.
        the assignment operator is represented here by ->
        the display command is represented by the # sign
        and "sqrd" means squared.  e.g.  Vsqrd  is V squared  (VxV)

"RANGE FORMULA"
"@ ="?->@
"VELOCITY ="?->V
"DISTANCE(METRES)"
(Vsqrd sin(2@))/9.8#
