Unformatted text preview: termine the value of i as t → ∞. (This is called the steady state current.) 12. If the voltage in the circuit in Exercise 11 above is switched off after 30 seconds, the current is given by the piecewise-defined function i(t) = 22 2 − 2e−10t if 0 ≤ t < 30 2 − 2e−300 e−10t+300 if t ≥ 30 This roast was enjoyed by Jeff and his family on June 10, 2009. This is real data, folks! 6.5 Applications of Exponential and Logarithmic Functions 393 With the help of your calculator, graph y = i(t) and discuss with your classmates the physical significance of the two parts of the graph 0 ≤ t < 30 and t ≥ 30. 13. In Exercise 7 in Section 2.3, we stated that the cable of a suspension bridge formed a parabola but that a free hanging cable did not. A free hanging cable forms a catenary and its basic ex + e−x shape is given by y = . Use your calculator to graph this function. What are its 2 domain and range? What is its end behavior? Is it invertible? How do you think it is related to the function given in Exercise 5 in Section 6.3 and the one given in the answer to Exercise 7 in Section 6.4? When flipped upside down, the catenary makes an arch. I...
