In problem #2 you are asked to find the slope of the tangent line to the graph of F(x)=₀^x t² (t³+36) dt at the point (2,1568) and use the tangent line to approximate the value of F(1.9) 

The correct statement of this problem is to find the slope of the tangent line to the graph of F at the point   (4, 1568) and use it to approximate the value of           F(3.9).  That is the x coordinate should be 4 and not 2.  Sorry for the typographic error.  Thanks to etl for pointing it out.
