A GRAPHING CALCULATOR IS REQUIRED FOR THIS QUESTION.
You are permitted to use your calculator to solve an equation, find the derivative of a function at a point, or calculate the value of a definite integral. However, you must clearly indicate
the setup of your question, namely the equation, function, or integral you are using. If you use other built-in features or programs, you must show the mathematical steps necessary to
produce your results. Your work must be expressed in standard mathematical notation rather than calculator syntax.
Show all of your work, even though the question may not explicitly remind you to do so. Clearly label any functions, graphs, tables, or other objects that you use. Justifications require
that you give mathematical reasons, and that you verify the needed conditions under which relevant theorems, properties, definitions, or tests are applied. Your work will be scored on
the correctness and completeness of your methods as well as your answers. Answers without supporting work will usually not receive credit.
Unless otherwise specified, answers (numeric or algebraic) need not be simplified. If your answer is given as a decimal approximation, it should be correct to three places after the
decimal point.
Unless otherwise specified, the domain of a function f is assumed to be the set of all real numbers x for which f (x) is a real number.
A student programs a robot to move across a flat surface over the time interval 0 <t < 20 seconds. The position of the robot at time t seconds is given by the parametric equations
x (t) = 3t + sin t and y (t) = 3 cos(t – sint), where x (t) and y (t) are measured in meters. The derivatives of these functions are given by x' (t) = 3 + cos t and
y' (t) = –3 sin(t – sin t) · (1 – cos t).
(a) Write an equation for the line tangent to the path of the robot at time t = 4 seconds.
