Questão 2336120

𝑓′(𝑥) = \(\frac{2\ senx\ \cos x}{\left(1+sen^2x\right)\left(1+\cos^2x\right)}\)

𝑓′(𝑥) = \(\frac{2\ senx\ \cos x}{\left(1-sen^2x\right)\left(1-\cos^2x\right)}\)

𝑓′(𝑥) = \(\frac{6\ senx\ \cos x}{\left(1-sen^2x\right)\left(1-\cos^2x\right)}\)

𝑓′(𝑥) = \(\frac{6\ senx\ \cos x}{\left(1+sen^2x\right)\left(1+\cos^2x\right)}\)
