cot 180

OpenStudy (anonymous):

Cot = 1/tan

OpenStudy (anonymous):

Cot 180 = 1/tan (180). This is undefined, as tan(180) = 0 and you can't divide by zero.

OpenStudy (jdoe0001):

\(\bf cot(180^o)\implies \cfrac{cos(180^o)}{sin(180^o)}\implies \cfrac{-1}{0}\)

OpenStudy (anonymous):

so your saying that it cos=180 and sin=180

OpenStudy (jdoe0001):

?

OpenStudy (jdoe0001):

\(\bf cot(\theta)\implies \cfrac{cos(\theta)}{sin(\theta)}\)

OpenStudy (anonymous):

when you did it you put both 180

OpenStudy (jdoe0001):

yes

OpenStudy (jdoe0001):

\(\bf cot({\color{blue}{ whatever}})\implies \cfrac{cos({\color{blue}{ whatever}})}{sin({\color{blue}{ whatever}})}\)

OpenStudy (anonymous):

so how did you do the part where you equal it to -1

OpenStudy (jdoe0001):

mat

OpenStudy (anonymous):

Those are values given by the Unit Circle.

OpenStudy (jdoe0001):

woops... darn... look at your Unit Circle

OpenStudy (anonymous):

so you used to X over the y

OpenStudy (anonymous):

okay now i got it
