Question

If sin a =1/2 then what is the value of cot a

Answer 1

Answer:

$sina = \frac{1}{2} = \frac{perpendicular}{hypotenuse} \:$

By pytgagors theorem ;

${pq}^{2} = {pr}^{2} + {rp}^{2} \\ {2}^{2} - {1}^{2} = {rp}^{2} \\ \sqrt{3 } = rp$

$\cot(a) = \frac{1}{ \tan(a) } = \sqrt{3}$

Answer 2

Answer:

first we draw draw triangle ABC

THEN USSING PYTHAGORES THEOREM
