2.  We now know how to differentiate sin x and x 2, but how do we differentiate a composite function, such as sin (x 2 -4)?

4.  An object moves along the x –axis so that its position at any time t>0 is given by x(t)= cos(t 2 +1).  Find the velocity of the object as a function of t.

5. 

6.  Differentiate sin (x 2 + x) with respect to x.

7.  We sometimes have to use the chain rule two or more times to find the derivative.

8.  Find the dervative of g(t) = tan (5 - sin2t).

10.  When evaluating cos and sin functions on your TI- calculator, what mode should it be in, radian or degree?
