[tex]f(x)=3\sin^2(x)\Rightarrow f'(x)=3\cdot \left(\sin^{2}\left(x\right)\right)'=3\cdot 2\cdot \sin\left(x\right)\cdot \left(\sin\left(x\right)\right)'=\\=6\,\cos\left(x\right)\,\sin\left(x\right)\Rightarrow f'(-4)=-6\cos 4\sin 4=-3\sin 8[/tex]
Ответ:
Объяснение:
[tex]f'(x) = (3\sin^2(x))' = 3 \cdot 2\sin(x) \cdot (\sin(x))' = 6 \sin(x) \cos(x)[/tex]
[tex]f'(-4) = 6 * \sin (-4) * cos(-4) = -6* \sin (4) * cos(4) = -3* \sin (8) \approx -3[/tex]
