Verify the formula by differentiation. S sec (9x+5)dx= tan (9x + 5) + C 9 Which function should be differentiated? 1 A. tan (9x + 5) + C 9 B. sec(9x+5) Use the Chain Rule (using f(g(x))) to differentiate. Recall that differentiating a constant, such as C, results in 0. Therefore, C will not influence choosing appropriate definitions for f and g. Choose appropriate definitions for f and g below. O A. f(x) = tan (x + 5); g(x) = 9x 1 / B. f(x)= tan (x); g(x) = 9x +5 f(x) = - - t O C. f(x) = 9x; g(x) == tan (x+5) 1 O D. f(x) = 9x +5; g(x) = tan (x) Find the derivatives of each of the functions involved in the Chain Rule. f'(x) = and g'(x)=
