part 4 please.

Final Draft_A.Gonzalez - Google Docs Fall 2021 MATH 150B- The function, F(x) = 3 cos x has derivatives f ' ( x ) = 3 sin (x -3 sin c f " ( x ) = -3 cos (x -3 cos r f ""(x) = 3sin (x 3 sin a and ((4) (x) = 3 cos (x) 3 cos Part 2 of 4 With a = 9x, f(97) = -3 -3 , f'(97) = 0 0 , f"(97) - 3 3 f "(9x) = 0 0 , and ((4)(97) = -3 -3 Part 3 of 4 Therefore, the Taylor Series begins - 3 V - 3 + 0 0 ( X - 9 7 ) + 3 V 3 ( x - 97) 2 + 0 0 ( X - 97) 3 2! 3! - 3 9 -3 (x - 97) 4 + .... 4 Part 4 of 4 Thus, the general formula is E n = 0
