MATH 105 FINAL EXAM April 13, 2010
Name:
Your grade is based on correctness, completeness, and clarity on each
exercise. You may use a calculator, but no notes, books, or other students.
Good luck!
1.) (15 pts.) Compute the following derivatives, using any valid techniques you like. (Be
sure to show enough steps so that it is clear which techniques you are using.)
a.) (5 pts.) f(x) = π+extan x
b.) (5 pts.) p(t) = 1
t+1
1 + t2
c.) (5 pts.) y=xcos x
1
2.) (15 pts.) Consider the integral Z2
1
(x+ 1) dx.
a.) (5 pts.) Interpret the integral as “area under a curve”. Draw the graph with area
shaded in, and use geometry to compute the signed area.
b.) (5 pts.) Evaluate the integral using the Fundamental Theorem of Calculus.
c.) (5 pts.) Are your answers the same or different? Explain why your answers should, or
should not, be the same.

3.) (15 pts.) Consider the integral Z2
1
1
x2dx.
a.) (5 pts.) Approximate the area under the curve using the a trapezoid sum with two
equal subintervals. In your approximation, use at least two digits after the decimal
point.
b.) (5 pts.) Evaluate the integral using the Fundamental Theorem of Calculus.
c.) (5 pts.) Are your answers the same or different? Explain why your answers should, or
should not, be the same.
