Q1.

If f (ac) = (a2 + 4x + 3) , then f' (ac) = f' ( 4 ) =Evaluate the following derivatives where (1 represents a constant real number: d 4 (c) E [cos (an: )] gnaw = :1 H Given f(2) = (9 ac 2 + 7) 3 Find f' (ac) f' (x) =\fUse the chain rule to find the derivative of y = 4e - 6x5 Use e^x for e". dy = dx
