Show all work for credit. Do all your work neatly on the paper provided.
Write your name on each sheet you turn in. I will not grade any
work done on the test sheet. When you are finished turn in all sheets
including the test. Good Luck.
- Approximate the area of the region bounded by y = 4x, the x-axis,
the line x = 0, and the line x = 2. Divide the interval [0,2] into 4
subintervals of equal length and use a convenient point in each subinterval,
to determine the areas of the chosen collection of rectangles.
- Evaluate the following sums:
(a) åj = 13 j3
(b) åj = 35 [j/( j+1)]
- Evaluate the following integrals:
- ò([(-3)/( x[3/ 11])] + [2/( x3/9)])dx
- ò23 (s-1)(s-2)ds
- ò49 [(x+1)/( Öx)]dx
- ò-21 |x|dx
- ò(sec2x-secxtanx)dx
- Let F(x) = ò1x2 [1/( t2)] dt. Find F¢(x).
- Carry out the indicated integration (Use substitution when necessary)
- òx2(11+2x3)1/3dx
- ò[2x/( [Ö(1+x2)])] dx
- òsin2x cosx dx
- Find the area bounded by y = (x-1)2+2, the x-axis, the line x = -1,
and the line x = 3.
(BONUS 5pts) Let L(x) be a function which has the property that
L¢(x) = 1/x.
Find ò[sinx/ cosx] dx
in terms of L.
