V64x2 49 Evaluate the integral: dx (A) Which trig substitution is correct for this integral? 7 Ox = sin (0) 1 Ox = 64 -sec(0) 7 Ox = -sec(0) 49 Or = 64 -sec(0) 8 Ox = =sec(0) (B) Which integral do you obtain after substituting for a? Note: to enter 0, type the word theta. do C) What is the value of the above integral in terms of 0? + C (D) What is the value of the original integral in terms of ? Note: WAMAP does not recognize the inverse secant (arcsec) function. You will need to use another inverse trig function when you fill in your answer below. - C
