Find the differential of each function. Function X Symbols (a) y = x- sin(4x) Relations dy = 2x sin (4x ) + cos( 4x) . 4x Sets X VO Vectors (b) y = In( V 2+ +2) Trig Greek X dy = Help 2+x2 X Enhanced Feedback Please try again. Keep in mind that the differential of y = f(x) is defined as dy = f'(x) dx. Make sure you apply the Product Rule when f is a product and use the Chain Rule when fis a composition of functions
