[tex]\cos(60) = \frac{1}{2}[/tex]


[tex]\cot(x) = \frac{1}{ \tan(x) } [/tex]



[tex]\tan(30) = \frac{ \sqrt{3} }{3} = \frac{1}{3} \sqrt{3}[/tex]


[tex]\cot(30) = \frac{1}{ \frac{ \sqrt{3} }{3} } = \frac{3}{ \sqrt{3} } = \frac{3}{3} \sqrt{3} = \sqrt{3} [/tex]


[tex]\sin(45) = \frac{1}{2} \sqrt{2} [/tex]
