The answer is 4! you move 4b to the 5b and subtract which gives you 1b and then you subtract 1 from five giving you 4 and 4/1=4
Y = x⁵ sin(2x ) cos(4x)
y' = d/dx (x⁵ sin (2x) × cos (4x) + x⁵ sin(2x) ). ×
d/dx (cos(4x) )
y' = 5x⁴ sin(2x) cos(4x)+2x⁵ cos(2x) cos(4x) -4x⁵ sin(2x) sin(4x)
Coin 1 is Q, the very top coin is N and the one below that is Q. For the bottom coin 2 that's N and the very bottom is also N and the one on top of the very bottom is Q. I hope that helped!
