Problem 1. Using the equation for the two dimensional trajectory of a projectile; 2 gx 2wcos(のア z=zo + xtan (e) where z is the vertical position, zois the initial launch altitude, x is the horizontal position, g is the gravitational acceleration on Earth (g 9.81 ms-2), u is the initial launch velocity, and θ is the initial launch angle: a) Create a MATLAB function file called ‘proj traj’ that inputs the initial launch angle,
