For the given values of initial velocity of projection and angle of inclination of the plane, the maximum range for a projectile projected upwards will be obtained, if the angle of projection is

α = π/2 + β/2

α = π/4 - β/2

α = β/2 - π/2

α = π/2 + β/2

α = π/4 - β/2

α = β/2 - π/2

Cartesian form of the equation of catenary is

y = c tan x/c

y = c sin x/c

y = c sinh x/c

y = c cosh x/c

y = c tan x/c

y = c sin x/c

y = c sinh x/c

y = c cosh x/c
