    1.R is the region that lies between the curve y = (1 /( x2 + 4x + 5) ) and the x-axis from x = -3 to x = -1. Find:
    (a) the area of R,
    (b) the volume of the solid generated by revolving R around the y-axis.
    (c) the volume of the solid generated by revolving R round the x-axis.

    2.Evaluate: ∫ sinh6 x cosh xdx.
