tentukan nilai sin 30derajat+ cos 30 derajat per sin 30 derajat - cis 30 derajat

[tex] \frac{ \sin(30) + \cos(30) }{ \sin(30) - \cos(30) } = \frac{ \frac{1}{2} + \frac{1}{2} \sqrt{3} }{ \frac{1}{2} - \frac{1}{2} \sqrt{3} } = \frac{ \frac{1 + \sqrt{3} }{2} }{ \frac{1 - \sqrt{3} }{2} } = \frac{1 + \sqrt{3} }{1 - \sqrt{3} } = \frac{1 + \sqrt{3} }{1 - \sqrt{3} } \times \frac{1 + \sqrt{3} }{1 + \sqrt{3} } = \frac{4+ 2 \sqrt{3} }{1 - 3} = - 2 - \sqrt{3} [/tex]
