+# Homework #2
+## due 2/3/17
+
+1. 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. 
+
+    ![projectile(v_mag,theta) predicts the height of the projectile based upon initial
+velocity and position, as see in the Figure](projectile.png)
+
+2. Clone your 'homework_1' repository to your own computer. Now, we want to create a
+function that uses kinematic formulas to predict the path of a projectile. The dimensions
+are taken from official dart board dimensions
+[darts](http://dartbrokers.com/dartboard-height.html). 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.*
