Use the quotient rule to find the derivative of 6ez + 8 4x5 - 7x7 Use e^x for e". You do not need to expand out your answer. Be careful with parentheses!\f5 tan c If f@) = then f'(x) = f'(1)4 sin r Let f (x) = 6 sina + 4 cos c Then f'(x) : The equation of the tangent line to y = f(x ) at a = can be written in the form y = ma + b where m = and b =Find the 57th derivative of the function f(x) = cos(x). The answer is functionLet HI) = 10$ | 6 113'. Then the equation of the tangent line to the graph of x] at the point {0, 5) is given by y = m: + b for
