    1. For the equation ?(x)= x^(1/2)
    a) Find the Taylor polynomial of degree 4 of at c = 4
    b) Determine the accuracy of the polynomial at x = 2.

    2. Find the Maclaurin series in closed form of
    a) ?(x)=((1) / ((x+1)^2)
    b) ?(x)=ln ((x^2)+1)

    3. Use the chain rule to find dw / dt, where
    w = x^2 + y^2 + z^2, x=(e^t) cos t, y=(e^t) sin t, z=(e^t), t=0.

    4. Find the critical points and test for relative extrema:
    ?(x,y)=2(x^2)+2xy+(y^2)+2x-3

    5. Maximize ?(x,y)= (6-(x^2)-(y^2))^(1/2) given the constraint
    x+y-2=0.
