Math 121  Final Exam Study Guide
 Use the table to simplify the expressions. Three parts.
 Consider a triangle with the sin, cos, and tan of three angles given in terms of a, b, and c.
Use that information to express the stated quantities in terms of a, b, and c. Three parts.
 Use the sketch of the function to find the limits. Also tell whether the function is
continuous, differentiable, and integrable at a point or on an interval. Eight parts.
 Find the limits of algebraic expressions. Show work where necessary. Six parts.
 Find the limits of trigonometric expressions. Show work where necessary. Three parts.
 A graph of a function and its derivative are shown. Label the function as f and the
derivative as g. Three parts.
 Use the table to evaluate and simplify the derivatives. Six parts.
 Find and simplify the derivatives of the algebraic functions. Four parts.
 Find and simplify the derivatives of the trigonometric functions. Four parts.
 Find dy/dx by implicit differentiation.
 Classify each critical point as a relative maximum, relative minimum, neither, impossible,
or not enough information given to determine. Assume that the function is continuous
and has only one critical point. Five parts.
 Determine by inspection whether the function on the interval will have an absolute
maximum, absolute minimum, both, neither, or not enough information is given. Three
parts.
 Find all absolute extrema, if any, on the stated interval.
 Sketch a continuous function with the given properties.
 Express the limit as a definite integral.
 Express the sum in closed form. Factor your answer completely.
 Write the sum in sigma notation. Do not evaluate.
 Evaluate the integral with algebraic integrands. Four parts.
 Evaluate the integral with trigonometric integrands. Four parts.
 Sketch the region enclosed by the curves and find its area.
 Sketch the region enclosed by the curves and find the volume of the solid generated when
it is rotated about an axis.
 Find the exact arc length of the curve on the interval.
 Find the work required to stretch a spring.
Notes:
 Problems are similar to problems off of old tests in most cases. I looked at the old tests
when making up the final.
 The final exam is open notebook. You may have any notes, homework, handouts, tests,
or study guides in your notes. You may not photocopy the book and put it into your
notes. You may (and should) go back and reinforce your notes in the areas they're weak.
 If you want to know what your final grade in the class is before the grade cards come out,
write your email address at the top of your test and I will email your grade once I have it
computed.
 The final exam is worth 200 points.
