1) \T(Total: 1.0 pts) Lembre do truque para derivar o arcsen:

$c = \cos θ, s = \sen θ, θ = \arcsen s$,

$\frac{ds}{dθ} = c = \sqrt{1-s^2},
 \frac{dθ}{ds} = \frac1c = \frac{1}{\sqrt{1-s^2}},
 \frac{d}{ds} \arcsen s = \frac{1}{\sqrt{1-s^2}}.
$,

Use algo parecido para calcular $\frac{d}{dx} \arctan x$.

\bsk

2) \T(Total: 1.0 pts) Explique por que $$\Intx{-1}{1}{x^{-4}} ≠ \Difx{-1}{1} {\frac{x^{-3}}{-3}}.$$

3) \T(Total: 2.0 pts) Calcule $$\Intx{-1}{2}{\frac{1}{1+|x|}}.$$

4) \T(Total: 2.0 pts) Calcule $$\intx {\frac{x^2}{x^2 - 4x - 5}}.$$

5) \T(Total: 3.0 pts) Calcule por substituição trigonométrica:

a) \B(1.0 pts) $$\intx {\frac{1}{1+x^2}}$$

b) \B(2.0 pts) $$\intx {\frac{x^2}{\sqrt{1-4x^2}}}$$

% 6) \T(Total: 1.0 pts) Calcule $$\intx {(2x+3) \sen (4x+5)}.$$
6) \T(Total: 1.0 pts) Calcule $$\intx {x \sen (4x+5)}.$$
