If a coffee filter is dropped, its velocity after t seconds is given by v(t)=4(10.0003t) feet per second. What is the terminal velocity, and how long does it take the filter to reach 99 of terminal velocity? Use a table increment of 0.1 and given your answer to the nearest tenth of a second.
Use an appropriate trig substitution to integrate x/sqrt(9-x2) dx. Clearly show how your work with simplifying the denominator, replacing the differential and show how you convert the answer back from theta to x. Use your trig substituiton to label the right triangle below to help in conversion.
Use the Substitution Method to evaluate the definite integral. (In x)* dx
Write the definite integral for finding the indicated arc length or surface area. Then use the integration capabilities of a graphing utility to approximate the arc length or surface area. A fleeing object leaves the origin and moves up the y-axis. At the same time, a pursuer leaves the point (1, 0) and always moves toward the fleeing object. The pursuer’s speed is twice that of the fleeing object. The equation of the path is modeled by as attached. How far has the fleeing object traveled when it is caught? Show that the pursuer has traveled twice as far.
