double angle Identities


cot theta= 3 lies in quad III

 

[happy]

What's the complete problem?

 

[Unco]

Is it \(\displaystyle \cot{\theta} = 3\); solve for \(\displaystyle \theta\) where \(\displaystyle \theta\) lies in quad 3?

If that's the case, no double angle identities are necessary.

Just write in terms of \(\displaystyle \tan{\theta}\) and solve for quad 3.
