{\bf Dicas:} 1) Você provavelmente vai precisar de pelo menos duas
mudanças de variável pra chegar no resultado final. 2) No curso nós
vimos dois modos de fazer mudanças de variável de um jeito legível: um
modo usava chaves sob subexpressões e o outro modo usava ``caixinhas
de anotações'' como a abaixo,
%
$$\bmat{
u = \sen x \\
\frac{du}{dx} = \frac{d}{dx} \sen x = \cos x \\
\cos x \, dx = du \\
x = \arcsen u \\
}
$$
em que todas as outras linhas da caixinha eram consequência da
primeira.

Lembre que no curso nós vimos que existem várias noções diferentes do
que é ``simplificar uma expressão''... por exemplo, no ensino médio os
professores exigem que a gente ``simplifique''
$\frac{1}{11} + \frac{1}{12} + \frac{1}{13}$ pra $\frac{661}{3036}$,
mas em Cálculo 2 a gente geralmente considera
$\frac{1}{11} + \frac{1}{12} + \frac{1}{13}$ mais ``simples'' do que
$\frac{661}{3036}$.

Lembre que nós vimos que o ``método'' para resolver EDOs com variáveis
separáveis --- ``EDOVSs'' --- pode ser escrito como a demonstração
$\ga{[M]}$ abaixo, e a ``fórmula'' para resolver EDOVSs pode ser
escrita como $\ga{[F]}$:
\bsk
$\ga{FOO}$
}\anothercol{
Quando a gente quer criar exercícios de EDOVSs que sejam fácil de
resolver a gente começa escolhendo $G(x)$ e $H(y)$, não $g(x)$ e
$h(y)$.
Digamos que $G(x)=x^4+5$ e $H(y)=y^2+3$.
\msk
a) \B (0.5 pts) Diga qual é a EDO da forma
$\frac{dy}{dx} = \frac{g(x)}{h(y)}$ associada a esta escolha de
$G(x)$ e $H(y)$. Chame-a de $(*)$. Não esqueça do ``Seja''!
\ssk
b) \B (0.5 pts) Escolha uma função $H^{-1}$ adequada. Defina ela com
um ``Seja'' e verifique que ela obedece o que esperamos dela.
\ssk
c) \B (1.0 pts) Encontre a solução geral da EDO $(*)$. Chame-a de
$f(x)$ e defina ela com um ``Seja''.
\ssk
d) \B (1.0 pts) Verifique que essa função $f(x)$ obedece $(*)$.
\ssk
e) \B (1.0 pts) Encontre uma solução da EDO $(*)$ que passe pelo
ponto $(x_1,y_1)=(1,2)$. Chame-a de $f_1(x)$ e defina-a com um
``Seja''.
\ssk
f) \B (1.0 pts) Verifique que a sua $f_1(x)$ realmente passa pelo
ponto $(x_1,y_1)$.
