When a pilot banks an aircraft moving at a speed v, in metres per second, at an angle ,
the radius of the turn that results is given by the formula r = v^2/g tan (22/7/2 - )
, where g is
the acceleration due to gravity, or 9.8 m/s2
. Use an appropriate equivalent
trigonometric expression to prove that this formula can be simplified to r = v^2 /g tan
what is the appropriate equivalent trigonometric expression
