Find the exact value of the expression without using a calculator. cot Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. cot (Simplify your answer, including any radicals. Use integers or fractions for any numbers in the expression.) O B. The answer is not defined.The volume V(t) of air in a particular animal's lungs t seconds after exhaling is given approximately by the following. V(t) = 0.38 -0.29 cos -, Osts8 0.6- The graph for two complete respirations is shown on the right. 0.4- 0.2- O - 0 1 2 3 4 5 6 7 8 Find the exact value of the following. A calculator is not needed to evaluate the angle. Use the graph to verify your answer. V(0) = V(1) = V(2) = V(3) = V(7) = (B) Use a calculator to find the following. V(3.5) = (Round to three decimal places as needed.) V(5.7) = (Round to three decimal places as needed.)Use a calculator in radian mode to find the value of the expression to four decimal places. sec sec 5 (Round to four decimal places as needed.)Use a calculator set in degree or radian mode, as appropriate, to find the value of the expression to four decimal places. sin 0.3 . . . sin 0.3 ~ (Round to four decimal places as needed.)Recall that it radians corresponds to 180. Mentally convert the given radian measure to degree measure. TC 6 - rad rad = (Simplify your answer.)
