Q) if \(sinA=\frac{1}{2}\), then the value of \(cotA\) is

• 1) (a) \(\sqrt[2]{3}\)
• 2) (b) \(\frac{1}{\sqrt[]{3}}\)
• 3) (c)\(\frac{\sqrt[]{3}}{2}\)
• 4) (d) 1

as given in the question sinA= 1/2,
we know \(cotA=\frac{cosA}{sinA}\)
\(cosA=\sqrt[]{1-sin^A}\)
\( \implies \) cosA=\(\sqrt[]{1-\frac{1}{4}}\) =\(\sqrt[]{\frac{3}{4}}\)
\( \implies \) cotA=cosA/ssinA=\(\sqrt[]{3}\)
