cosec² theta =2 cot theta
1+ cot² theta -2 cot theta =0
1²+ cot² theta - 2*cot theta *1=0
(1-cot theta)²=0
1- cot theta =0
therefore
cot theta = 1
cot theta = cot 45
theta = 45 degrees
1+ cot² theta -2 cot theta =0
1²+ cot² theta - 2*cot theta *1=0
(1-cot theta)²=0
1- cot theta =0
therefore
cot theta = 1
cot theta = cot 45
theta = 45 degrees
