Evaluate the integral. Show that the substitution $$x=4\sin (?)$$ transforms $$I$$ into $$?d?$$, and evaluate $$I$$ in terms of $$?$$. $$I=?\frac{dx}{\sqrt{16?x^2}}$$ (Use symbolic notation and fractions where needed. Use $$C$$ for the arbitrary constant. Absorb into $$C$$ as much as possible.) Incorrect Evaluate $$I$$ in terms of $$x$$. (Use symbolic notation and fractions where needed. Use $$C$$ for the arbitrary constant. Absorb into $$C$$ as much as possible.) Show the integral in which the substitution $$x=\frac{2}{7}\tan (t)$$ transforms $$I=?\frac{dx}{\sqrt{49x^2+4}}$$ (Use symbolic notation and fractions where needed.) $$I=?$$ Evaluate the integral $$I$$ in terms of $$t$$. (Use symbolic notation and fractions where needed. Use $$C$$ for the arbitrary constant. Absorb into $$C$$ as much as possible.) $$I=$$ Evaluate the integral $$I$$ in terms of $$x$$. (Use symbolic notation and fractions where needed. Use $$C$$ for the arbitrary constant. Absorb into $$C$$ as much as possible.) $$I=$$
