d/(dθ)(tan^2(θ))

解答

\frac{d}{d θ} (tan^{2} (θ))

2 tan (θ) sec^{2} (θ)

求解步骤

\frac{d}{d θ} (tan^{2} (θ))

使用连锁律:

2 tan (θ) \frac{d}{d θ} (tan (θ))

= 2 tan (θ) \frac{d}{d θ} (tan (θ))

\frac{d}{d θ} (tan (θ)) = sec^{2} (θ)

= 2 tan (θ) sec^{2} (θ)

y^{^{''}} + 11 y^{^{'}} + 24 y = 0, y (0) = 0, y^{^{'}} (0) = - 7

x \to 0 lim (\frac{( 9 ^{x} - 3 ^{x} )}{x})

\int x \cdot ln^{3} (x) d x

x \to 2 lim (2 x^{2} - 3 x + 5)
