<b class="bfseries">Part 1: Function Types</b>
</p>
<p>
For each of the following functions, specify the type of its <b class="bfseries">output</b>. You can assume each function is called with an appropriate argument, as specified by its docstring. </p>
<p>
If the output can be either an int or a float, select num, which isn't a real Python type, but which we'll use to indicate that either basic numeric type is legal. </p>
<p>
In fact, in Python, booleans True and False can be operated on as if they were the integers 1 and 0; but it is ugly and confusing to take advantage of this fact, and we will resolutely pretend that it isn't true. </p> <!-- so why even mention it? -->
<p>
<section class="hints">
<div class="collapsible">
<header>
<a href="#" id="id41">What are those lines under the function definitions?</a>
</header>
<section id="id41">
<p>
In this and future problems, you'll see function definitions that look like this: </p>
<pre>
def a(x):
'''
x: int or float.
'''
return x + 1
</pre>
<p>
What are those three lines between <code>def a(x):</code> and <code>return x + 1</code>? These lines are called the <i class="it">docstring</i> of the function. A docstring is a special type of comment that is used to document what your function is doing. Typically, docstrings will explain what the function expects the type(s) of the argument(s) to be, and what the function is returning. </p>
<p>
In Python, docstrings appear immediately after the <code>def</code> line of a function, before the body. Docstrings start and end with triple quotes - this can be triple single quotes or triple double quotes, it doesn't matter as long as they match. To sum up this general form: </p>
<pre>
def myFunction(argument):
"""
Docstring goes here. Explain what type argument(s) should have, and what your function
is going to return.
"""
&lt; Code for your function (the body of the function) goes here &gt;
</pre>
<p>
As you begin coding your own functions, we strongly encourage you to document all your functions by using properly-formatted docstrings! </p>

Below is a transcript of a session with the Python shell. Assume the functions from Part 1 (above) have been defined. Provide the type and value of the expressions being evaluated. If evaluating an expression would cause an error, select NoneType and write 'error' in the box. If the value of an expression is a function, select function as the type and write 'function' in the box. </p>

<p>
Why do bicycles benefit from having larger wheels when going up a bump as shown in the picture? <br/>
Assume that for both bicycles:<br/>
1.) The tires have equal air pressure.<br/>
2.) The bicycles never leave the contact with the bump.<br/>
3.) The bicycles have the same mass. The bicycle tires (regardless of size) have the same mass.<br/>
</p>
</text>
<optionresponse texlayout="horizontal" max="10" randomize="yes">
<ul>
<li>
<text>
<p>The bicycles with larger wheels have more time to go over the bump. This decreases the magnitude of the force needed to lift the bicycle.</p>

<h2>Example: Symbolic Math Response Problem</h2>
<p>
A symbolic math response problem presents one or more symbolic math
input fields for input. Correctness of input is evaluated based on
the symbolic properties of the expression entered. The student enters
text, but sees a proper symbolic rendition of the entered formula, in
real time, next to the input box.
</p>
<p>This is a correct answer which may be entered below: </p>
<p><tt>cos(theta)*[[1,0],[0,1]] + i*sin(theta)*[[0,1],[1,0]]</tt></p>
<script>
from symmath import *
</script>
<text>Compute [mathjax] U = \exp\left( i \theta \left[ \begin{matrix} 0 &amp; 1 \\ 1 &amp; 0 \end{matrix} \right] \right) [/mathjax]
and give the resulting \(2 \times 2\) matrix. <br/>
Your input should be typed in as a list of lists, eg <tt>[[1,2],[3,4]]</tt>. <br/>
[mathjax]U=[/mathjax] <symbolicresponse cfn="symmath_check" answer="[[cos(theta),I*sin(theta)],[I*sin(theta),cos(theta)]]" options="matrix,imaginaryi" id="filenamedogi0VpEBOWedxsymmathresponse_1" state="unsubmitted">
