Is there a faster way to solve this improper integral?

Question basically is at top

#

I think you forgot to add as n approaches infinity

#

At the top

#

But otherwise it looks good

#

That’s what i would have done

#

Don’t know any faster way to go about it

And i see thank you

On a few limits you didn’t like 1. and 8. b

Quick question btw do u know when u use u sub are u suppose to redefine ur intervals?

next jay
#

I see ok

dreamy salmon
#

Bc ive never heard of that before

next jay
#

Yes and no

#

Redefining intervals just means you have whatever u is equal to, and you plug in your intervals in to the function that u is equal to.

#

In doing so you don’t have to sub back later

#

However since you are subbing back for u, redefining the intervals is unnecessary

#

Personally I think redefining is easier and quicker, cause sometimes you have some annoying functions to deal with in the end

So for like #3 i couldve put the interval from 110 to 10t+50

#

For the first one

#

And i wouldnt have to sub u back

#

Interesting

next jay
#

Not for improper integrals

#

Usually for improper you want to be subbing back since you have a variable as one of your intervals

#

Works either way but still

#

Ah i see

#
