Show that [infinity] 0 e−x9 is convergent. SOLUTION We can't evaluate the integral directly because the antiderivative of e−x9 is not an elementary function. We write [infinity] 0 e−x9 dx = 1 0 e−x9 dx + [infinity] 1 dx and observe that the first integral on the right-hand side is just an ordinar

Step-by-step explanation:

Just remember that

That is the most important part, therefore,

Since  

and the integral

is an integral over a bounded interval and

The integral

converges.

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.
