Answer:
value = 2
Step-by-step explanation:
so, we know that
tan45° = cot45° = 1
so, tan45 + cot45 = 2
therefore, A = 45°
now,
= tan¹²A + cot¹²A
= tan¹²45° + cot¹²45°
= (1)¹² + (1)¹²
= 1+1
= 2
looking forward for BRAINLIEST answer,
cheers!!

Answer:
2
Step-by-step explanation:
The given equation becomes tanA + 1/tanA = 2
gives, tan^2A - 2tanA + 1 = 0 ( by L.C.M method and cross multiplication )
Solving the quadratic equation, tanA = 1,1
Therefore, A = 45°
Now, tan^12 + cot^12
= 1^12 + 1^12
= 1 + 1
= 2
