integral of ae^((-x^2)/(5))dx=1 solve for a

Question

anonymous · Answer

$$a \int\limits_{}^{} e^{\frac{ -x ^{2}}{ 5 }}dx = 1$$
Is this right?

anonymous · Answer

Wouldn't you need to use Laplace transformations for this? (I forget how to solve it however it just seems like something I've seen before)

What class is this? Just wondering because I might be totally off on my answer.

anonymous · Answer

@megannicole51, we need some limits for the integral.

megannicole51 · Answer

there arent any

calc 2 at a university level

megannicole51 · Answer

it says enter 3 decimal points so its not a whole number

anonymous · Answer

with no limits of integration i can't imagine how you would do this problem
the integral could be almost anything
also i am fairly sure that you are not going to find a nice closed form for 
$$\int e^{-\frac{x^2}{5}}$$

@SithsAndGiggles  Can I take derivative both sides which lead to a =0? what's wrong if I do so?
