Another approach to the parabola problem, which may be of particular interest to calculus students, is that for a parabola to be the graph of y=ax^2+bx+c: c is the y-intercept (ie the height at the point where x=0) b is the slope of the tangent line at that point, and ...
e.g Angle for a given distance, maximum height, terminal velocity? Angle for a given distance In order to find out what is the angle to reach a certain distance, x, we need to loop this trajectory as many angles until it reaches the point (x,0). Therefore, I put the whole process ...
