  1. In-class exercise: Oh Suzanna song - first 15 notes.

  2. Where is Waldo 2D Graphics and solving the (x, y) or specifically (xcor, ycor) location of the turtle with who #2.
    Solve where is WALDO using ONLY the SINE (SOH).  Soh, soh what, sew, a needle pulling thread.
    Solve where is WALDO using ONLY the COSINE (CAH).  The crow went CAW, CAH. Ahhhh, CAaaahhhhh.
    
    
  3. Pythagorean theorem can be used along with the tangent to find out where is Waldo, where is the turtle with a certain who number.
    Solve where is WALDO using ONLY the TANGET (TOA).  I stubbed by TOE, TOA.
       
    square root(hyp squared) = square root( xcor squared + ycor squared )
    
    
       25 = 9 + 16
    
         2    2     2
        5  = 3  +  4    for a 3 by 4 right triangle with one leg length 3,
                                                       other leg length 4,
                                                  and hypotenuse length 5.
    In mathematics, the Pythagorean theorem, 
         is a fundamental relation in Euclidean geometry 
         among the three sides of a right triangle. 
    
    It states that the square of the hypotenuse (the side opposite the right angle) 
         is equal to the sum of the squares of the other two sides. 
    
    The theorem can be written as an equation relating 
         the lengths of the sides a, b and c, 
         often called the "Pythagorean equation":
    
         a^2 + b^2 = c^2,
    
         where c represents the length of the hypotenuse 
         and a and b the lengths of the triangle's other two sides (the legs).
