Solve the problem.The path of a projectile fired at an inclination ? (in degrees) to the horizontal with an initial speed v0 is a parabola. The maximum height H of the projectile is given by H = 
(1 - cos (2?))where g is the acceleration due to gravity.Show that the maximum height H can be written H = 
What will be an ideal response?
H = 
(1 - cos(2?)) = 
(1 - (1 - 2 sin2 ?)) = 
(2 sin2 ?) =
