Graphing A Sine Wave With Python Turtle

A further lesson on graphing equations

In a previous lesson we introduced the concept of graphing equations. In this lesson we are going to graph the equation of a sine wave.

Here’s the code:

import turtle as T
import math
T.width (5)
amplitude = 30
frequency = 6
frequency2 = 7
T.penup()
T.goto(-300,0)
T.pendown()
for i in range (-300,300,frequency):
    y = (math.sin(i))* (2*math.pi*amplitude)
    T.goto(i,y)
T.pencolor ("red")
T.penup()
T.goto (-300,0)
T.pendown()
for i in range (-300,300,frequency2):
    y = (math.sin(i))* (2*math.pi*amplitude)
    T.goto(i,y)
T.hideturtle()

The sine wave is an import concept in It in both pure and applied mathematics, as well as physics, engineering, signal processing and many other fields.We will be looking at this in more detail in subsequent lessons. For now experiment with changing the amplitude and the frequency.
