Question

If sin(0/2)=1/root2 then cot theta=

Answer 1

cot∅ = 0°.....................

Answer 2

Step-by-step explanation:

sin( theta /2 ) =1/root 2----------(1)

1/root 2= sin 45

then from equation (1)

sin(theta /2 ) = sin 45

if sin of some angles are equal then the angles are equal

theta /2 = 45

theta = 2*45 =90

cot (theta ) = cot 90 = 0

ans =0
