-- Uber l33t maths to calcluate the angle needed to throw a projectile a distance, given the altitude of the end point and the projectile's velocity

function AngleOfReach(distance, altitude, velocity)
	local theta = math.atan((velocity^2 + math.sqrt(velocity^4 -196.2*(196.2*distance^2 + 2*altitude*velocity^2)))/(196.2*distance))
	if theta ~= theta then
		theta = math.pi/4
	end
	return(theta)
end
