$- sin 2 x$ $-sin2x$

Explanation:

$differentiate using the chain rule$ $"differentiate using the "color(blue)"chain rule"$

$given y = f (g (x)) then$ $"given "y=f(g(x))" then"$

$dy/dx=f'(g(x))xxg'(x)larrcolor(blue)"chain rule"$

$y=1+(cosx)^2$

$dy/dx=2cosx xxd/dx(cosx)$

$color(white)(dy/dx)=-2sinxcosx=-sin2x$
