Precalculus

Flamo:

Hm?

Shadow:

If \[\tan (\frac{ \pi }{ 3 } - A) = \cot (\frac{ \pi }{ 3 })\] What is A? \[0 < A < \frac{ \pi }{ 2 }\]

Flamo:

Well, A is bigger then 0 and Smaller then Pie/2 right?

Flamo:

Than*

Shadow:

Yes, this has to do with Cofunction Identities.

Flamo:

Okay, So the pie is 3.14/2

Shadow:

That just means A is within the first quadrant of the unit circle

@bm717

bm717:

Yes?

Shadow:

Sarah :)

bm717:

Shadow :)

Shadow:

You know this question?

bm717:

You have to isolate the function and take the inverse

Shadow:

\[\cot \frac{ \pi }{ 3 } = \frac{ \sqrt3 }{ 3 }\] \[\tan \frac{ \pi }{ 3 } - A = \frac{ \sqrt 3 }{ 3}\] \[\frac{ \pi }{ 3 } - A = \frac{ \pi }{ 6 }\] \[-A = - \frac{ \pi }{ 6 }\] \[A = \frac{ \pi }{ 6 }\]

Shadow:

Good?

bm717:

Yeh, I think so.

bm717:

I’m on mobile but the work is right... I believe.

Shadow:

You're great. I don't have $200 for you, so I hope my thanks can suffice.

bm717:

LMAO I’ll be sending the bill to you in.a little bit.

Shadow:

Wow

bm717:

It might take a while however, knowing you live on el Hawaii

Shadow:

I'll find a way to pay you back

bm717:

You better.
