2017
1. Let f (x) = ,x2 + 3. Estimate f (1.02), using the linearization L(x) of the function f (x) at
the point a = 1.
2. Give the Riemann sum using n = 4 rectangles for ←1 3 e –ì dx. Use right-hand heights for the
rectangles. You should give an explicit formula, but you do not need to evaluate it numerically.
You may use sigma-notation if you wish.
3. A particle moves along a straight line, with velocity v(t) = 2t _ 3.
Find the net displacement between t = 1 and t = 3.
4. Evaluate ←ìì2 cos(t) dt.
5. Evaluate each of the following definite integrals.
a) ←1 2 cos(2t + 1) dt
b) ←0 1 dx
c) ←1 2 dx
6. Determine the indefinite integrals. You must show your work!
a) ← x ln(x ) dx32
b) ← e –ì sin(2x) dx
7. Determine the indefinite integrals. You must show your work!
