A student used the following trigonometric substitution. Let x = sec 8, dx = sec 0 tan de The student simplified the integral and gets: tan (0) + tan (0) + c Help the student with the right triangle to transition back to "x". Which of the following is accurate? 33 (x + 1) + (x+1) + c }(z 1) + (x 1) + c = - + c (-1) + ( -1) . (1-x) + (1-x) + c 1/
