integration

Did I do it correctly

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

I can't understand the question

Is it possible to send it here or write it a bit neater?

[tacit slate]

First line

[cold pebble]

Yee

[tacit slate]

That’s what I suppose to solve

[cold pebble]

I'm not able to read that

[tacit slate]

Man

[cold pebble]

sorry

just tell me

[tacit slate]

I’m writing it

Better

[cold pebble]

what's inside the integral

alr

[cold pebble]

alr

[tacit slate]

Oh wait

The cos inside the

Root

[cold pebble]

is?

[tacit slate]

Has 2x

Not x

[cold pebble]

ah ok

the first 3 lines are correct

the 4th line is also correct

but the final answer is wrong...

[tacit slate]

Ohhh

What did I mess up

[cold pebble]

$\cos^2{x} = \frac{1+\cos{2x}}{2}$

[south comet]

No Lifer (aka No Lifer)

[cold pebble]

which integrates to

[tacit slate]

That 1/2 is suppose to be outside the

Brackets

[cold pebble]

hmmm

[tacit slate]

Root(2)/2 ( integration cos2x + 1)

[cold pebble]

then you'd have 1/sqrt(2) outside right?

not sqrt(2)

[tacit slate]

Yep

U can cancel out

[cold pebble]

You wrote sqrt(2) instead of 1/sqrt(2) in your final answer

only mistake

[tacit slate]

I forgot to put

2 below

Root 2

[cold pebble]

then you're correct

good job

[cold pebble]

You alr know what you're doing

pretty soon these things will be really easy for you

[tacit slate]

I mean in my book it looks like they put wrong answer

I thought I did it wrong

So just wanted to make sure

[cold pebble]

ah ok

[tacit slate]

Yes will practice

More

[cold pebble]

alr

best of luck mate!

[tacit slate]

Thanks

Have a nice day
