Created page with "'''Objectives:''' * You will practice creating while loops * You will integrate loops into drawing graphics with Python's turtle * You will create a basic graphing calculator ''..."

New page

'''Objectives:'''
* You will practice creating while loops
* You will integrate loops into drawing graphics with Python's turtle
* You will create a basic graphing calculator

'''Resources:'''
* [http://docs.python.org/py3k/library/turtle.html Python Turtle Reference]

'''Directions:'''
# Name your file: '''turtleGrapher.py''':
# Set your turtle's speed to the fastest: '''speed(0)'''
# Prompt the user for the height of the window and store in a variable named '''height'''
# Prompt the user for the width of the window and store in a variable named '''width'''
# Change the dimensions of the window by using '''setup(width, height)''' and then '''screensize(width, height)'''
# Draw a line that represents the x-axis
# Draw a line that represents the y-axis
# Using textinput(), prompt the user to enter an equation (e.g. 2*x+3) and store it in a variable: '''eq'''
# Write a while loop where x starts at -width/2 and goes all the way through width/2
## Inside the while loop, use eval to get the y-value of the equation: '''y = eval(eq)'''
## Tell the turtle to goto(x, y)
# Tell the turtle window to exit when it is clicked

		+	'''Advanced: (Optional)'''
		+	* Once you have the basic calculator working, try to implement a zoom feature that draws the equation bigger
		+	* Draw the tick marks on the x and y-axes
