Question

cot(3x)= squareroot of 3
what is the solution set

Answer 1

what do you get ?
you'll get an error or similar message since angles can only of cosine detween -1 and 1

Answer 2

you should look at using

cot = 1/tan

so take the reciprocals of both sides and you get

\[\tan(3x) = \frac{1}{\sqrt{3}}\]

then find the arc tan

\[3x = \tan^{-1}(\frac{1}{\sqrt{3}})\]

hint... its an exact value angle from the 30, 60 right triangle

when you get the answer, divide it by 3 to find x

hope this helps

Answer 3

oops sorry - i misread the question!
