+# Lab: Plotting a Sine Wave
+
+Create and set up the turtle and the screen.
+
+Iterate the angle from 0 to 360.
+
+> Generate the sine value for each angle.
+> 
+> Move the turtle to that position (leave a line behind).
+
+_My note: the lab encouraged us to try other functions out, so I included a turtle drawing cosign._
+
+```text-x-python
+import math
+import turtle
+
+wn = turtle.Screen()
+wn.bgcolor('lightblue')
+
+turtle.setworldcoordinates(0, -1.25, 360, 1.25)
+
+fred = turtle.Turtle()
+fred.speed(10)
+fred.color('red')
+
+george = turtle.Turtle()
+george.speed(10)
+george.color('blue')
+
+for angle in range(361):
+    x = angle
+    y = math.sin(math.radians(angle))
+    fred.goto(x,y)
+    
+for angle in range(361):
+    x = angle
+    y = math.cos(math.radians(angle))
+    george.goto(x,y)
+
+wn.exitonclick()
+```
