find the slope of the tangent to the curve N 16 + 32 at u = 3 Find derivative of the function when u = 1.47 (7. 42 x2 - 2.75# )Products Some these can be multiplied out . for a few of these take the desivative both before and after multiplying out and Compare the two . E y = 1 ( 2 x - 3 ) #3 x +5 - 4 = 3 UN St x 2 y = Jx ( 3x - + 2 1 - 3 ) 3 N d ( 2x + 5 x ) ( x - 3 )
