Question

Calculate the integrals in Problems 72-74 by partial fractions and then by using the indicated substitution. Show that the results you get are the same. da: 72. :s ; substitution x = sin 0. In Problems 86-87, decide whether the statements are true or false. Give an explanation for your answer. dt can be made easier to evaluate by using the substitution t = 3 tan . 86. The integral 66. Graph three different functions, continuous on o sxs 1, and with the values in the table. The first function is to have exactly one zero in [0, 1], the second is to have at least two zeros in the interval [0.6, 0.8), and the third is to have at least two zeros in the interval [0, 0.6). 0.2 0.4 0.6 0.8 f(x) 1.00 0.90 0.60 0.11 -0.58 -1.46 X 1.0

please ignore the first photo and only answer #86 and #66
