Express the trigonometric ratios sin A,sec A and tan A in terms of cot A

$\large\bf{\underline{\color{indigo} Options,}}$

$(a) \: sin \: a \: = \: \frac{1}{ \sqrt{cot \: a \: + \: 1}} \\ sec \: a \: = \: \frac{ \sqrt{ {cot}^{2} a + 1} }{cot \: a} \\tan \: a \: = \: \frac{1}{cot \: a}$

$(b) \: sin \: a \: = \frac{1}{ \sqrt{ {cot}^{2} a + 1} } \\ sec \: a = \frac{ \sqrt{ {cot}^{2} a + 1} }{cot \: a} \\ tan \: a \: = \frac{1}{cot \: a}$

$(c) \: sin \: a \: = \: \frac{1}{ \sqrt{cot \: a - 1} } \\ sec \: a = \: \frac{ \sqrt{ {cot}^{2} a + sin \: a} }{cot \: a} \\ tan \: a \: = \frac{1}{cot \: a}$

(d) None of these
