Question

Solve, for θ in degrees 0° ≤ θ ≤ 360° : cotθ = 1

Answer 1

how would you write cot theta in terms of sin cos ?

Answer 2

i really don't know

cot theta = ??

Answer 4

i still dont get it

Answer 5

if you look at the pic
cot theta = cos theta/sin theta
\[\cot \theta =1 ~~ \rightarrow \frac{\cos \theta}{\sin \theta}=1\]
now look at the unit circle
at what degree cos divided by sin = 1 ?

Answer 6

360 ?

Answer 7

0 actually

Answer 8

x-coordinate = cos
and y-coordiante represent sin
so at 0 degree cos =1 and sin =0
so when you divide cos /sin
1/0 isn't equal to 1
1/0 is undefined
