Now that you have created your own repository, 'homework_1', that has a README.md file. +Create a new file in this repository called `setdefaults.m`. This file is a matlab/octave +script that will set default plotting parameters. In this file, add the following lines: + + ```matlab + set(0, 'defaultAxesFontSize', 16) + set(0,'defaultTextFontSize',14) + set(0,'defaultLineLineWidth',3) + ``` + + Commit the changes to your repository. + +2. Clone your 'homework_1' repository to your own computer. Create a function, +`projectile.m` that will calculate the location of an object with an initial velocity. The +function inputs are v_mag (initial speed), theta (initial angle). The output is the height +of the object 2.37 m from its starting position. Assume g=9.81 m/s^2 and its initial +height is 1.72 m. + + ```matlab + >> h=projectile(v_mag,theta) + + h= 1 + ``` + + In addition to the output of `h`-height at 2.37 m-plot the path of the object from its + initial position to its position at 2.37 m away from the start. *Note: use your + `setdefaults.m` to set the plot defaults before outputting the result.*
