Question

evaluate indefinite integral using the substitution method.........

Answer 1

nice that they tell you what method to use!

Answer 2

\[\int\limits_{}^{}e ^{2x ^{2}+1}xdx\]

Answer 3

lol. let u=2x^2+1

Answer 4

or be a wise guy and write as
\[e\int e^{2x^2}xdx\]

Answer 5

ignore me, do what sparkles says

Answer 6

Sorry for typing lol... we all have to start somewhere :)

Answer 7

\(u=2x^2+1, du=4xdx, \frac{1}{4}du=xdx\)

Answer 8

\[\left( e ^{2x ^{2}+1} \right)/4 + K\] ??????

Answer 9

um...no.

integral e^u du where u=2x^2+! and du=4xdx

Answer 10

ugh

Answer 11

yes and you can check that it is right by differntiating

Answer 12

why do i have a feeling this has an imaginary error function....o.O

Answer 13

which is it right or wrong lol

Answer 14

@myluv4u you have the right answer

Answer 15

thank you yay!!!

Answer 16

@igbasallote I think you missed the x multiplier like I did at first

Answer 17
