  1. Sketch the following functions and state the domain and range of each.


    2.

        Range is                                                                              Range is
     
     
     
     

    c. 

                Domain is
                Range is [- 1, 1]
     
     

  2. Find the line tangent to each function at the given x-value.
    1. at x = 2

      2.  

       

      So, the slope of the tangent line is - 12.
      Now, a point on the line is (2, - (2)3) = (2,- 8).

      So, the equation of the line is , which simplifies to .
       

    2. at x = p / 4

      3.  

      So, the slope of the tangent line is .

      Now, a point on the line is (p / 4, cos(p / 4)) = (p / 4,).

      So, the equation of the line is , which simplifies to .
       

    3. at x = 1

So, the slope of the tangent line is 0. This means that the tangent line is horizontal. Since it goes through the point (1, 81), the equation of the tangent line is y = 81.
 
  1. Evaluate the following integrals.

  2. Express the area of the shaded region on the right as:

  1. a  limit of a sum.


    2.  

     

                    
     
     

  2. a definite integral.

        

 
  1. Consider the following polynomials:

, , 
  1. What should be?


    2.  


     

  2. Graph through one at a time using a window that goes from x= -6 to x = 6 and from y = - 2 to y = 2. Can you see what function these polynomials are tending towards? Graph this function along with to see how close they are. Now zoom out to see that they are not so close after all.


    3.  

    The graph of should be very close to the graph of sin(x) in the window given.
     

  3. How many terms do you think we would need to get an exact match?

You would need an infinite number of terms to get the function sin(x).
