Applied Maths, projectiles

A projectile is fired with an initial speed u at an angle θ to the horizontal
up a slope that is at an angle α to the horizontal and moves in the gravitational field −gk with no air resistance or wind.
Find an expression for the range measured up the slope from where the projectile is released
Show that this range is maximum when θ = π/4 + α/2

Any help would be greatly appreciated :smile:
