Question

s

Answer 1

\[\cot=\frac{\cos}{\sin}\]

Answer 2

\[\cot \frac{ 3\theta }{ 2 }=\frac{ -\sqrt{3} }{ 3 }\]
\[\tan \frac{ 3\theta }{ 2 }=\frac{ -3 }{ \sqrt{3} }=-\sqrt{3}\]
\[\frac{ 3\theta }{ 2 }=\frac{ 5\Pi }{ 3 }\]

Answer 3

Thanks! Really appreciate it, I'll look back on my notes on you were able to do it

Answer 4

you may also look at the graph, then you can see the values of tan(x) will be undefined at some points in [0, 2pi)

Answer 5

cot^-1 (-4.1) is the same as cot (x) = -4.1

Answer 6

I will fan anyone who can help me with this answer please

Answer 7

plot of cot^-1. You'll notice it's only undefined at pi/2, -pi/2, pi, ...

Answer 8

you can translate your problem into -pi/2 to pi/2 if you want your calculator to give a answer.
