What would be the best thing to use replace with substitution in this case?
\[\int\limits_{}^{}x e^{-x^2} dx\]

Answer 2

Guess

Answer 3

\[x^{2}\]

Answer 4

close, - x^2

Answer 5

okay i'll try using -x^2

Answer 6

Got the answer!! Thank you!

Answer 7

\(u=x^2\) will work just fine, too. The sign of the exponent will generate a negative when you integrate \(e^{-u}\).

Answer 8

Okay thanks for that!
