Which of the following 3 derivatives are correct? i) If y = [ln( x 2 )] 2 , then y = 4 ln x x . ii) If y = sin 3 [(ln( 4 x )] , then y = 3 sin 2 ( 1 2 ln 4 x ) cos ( 1 2 ln 4 x ) 1 8 x . iii) If y = e csc 2 (3 x ) then y =- e csc 2 (3 x ) csc(3 x ) cot(3 x ) A) i) only B) ii) only C) i) and iii) only D) i) and ii) only E) None of these listed answers A)-D) is correct. [ 2 ] 2. Which of the following 3 derivatives are correct? i) If y = ln parenleftbigg cos x e 2 x- 1 parenrightbigg , then y = 1 2 tan x- 2 e 2 x e 2 x- 1 . ii) y = ln( e x- x ) , then y = 1- 1 x . iii) If y = ln( radicalbig 1 /x ) , then y =- 1 2 x . A) i) only B) iii) only C) i) and iii) only D) ii) and iii) only E) None of these listed answers A)-D) is correct....
