$y=e^{1-8x}$
$y=frac{cosx}{5x^{2}}$
$y=sin4x(2-6x)$
$y=sinfrac{x}{3} (2x+1)$$y=e^{2-7x}$

Answer 1

1)
$e ^{1 - 8x} times ( - 8)$
2)
$frac{ - sin(x) times 5x^{2} - cos(x) times 10x }{25x^{4} }$
3)
$cos(4x) times 4times (2 - 6x) + sin(4x) times ( - 6)$
4)
$frac{1}{3} times (2x + 1) + frac{x}{3} times 2$
5)
$e^{2 - 7x} times ( - 7)$
