[tex] \cos \theta = \frac {2} {3} and \frac {3\pi} {2} <\theta<2\pi [/tex] then determine the exact value of [tex] \frac {1} {\cot\theta} [/tex]
I did this question using sin^2+cos^2=1 subbing in cos and then solving for sin when i got both values i realized that 1/cot theta = tan theta which is (sin theta)/(cos theta)
I got my answer to be squareroot 5/2 is this correct?
