Question

$\log(\cos^{- 1}x) + c$

• A. $- \log(\cos^{- 1}x) + c$
• B. $- \frac{1}{2(\cos^{- 1}x)^{2}} + c$
• C. $\int_{}^{}{x^{3}e^{3x^{2} + 5}}dx$
• D. $x^{2} = t$

Answer 1

Answer: (C)

$\int_{}^{}{x^{3}e^{3x^{2} + 5}}dx$

Answer 2

$\log\left( \frac{1}{2\log x - x} \right) + c$

$\log(x - 2\log x) + c$.
