Question
If tan2° = x/y, find sec²88°/(1 + cot²88°)
Answer
Explanation
First of all let's simplify
We know that the relation between cot∅ and cosec∅ is given by the identity
1 + cot²∅ = cosec²∅
→ 1 + cot²88° = cosec²88°
Hence,
Now, we know that tan∅ = sec∅/cosec∅
→
Also, tan∅ = 1/tan(90 - ∅)
→ tan(88°) = 1/tan(2°)
→ tan²(88°} = 1/tan²(2°)
→ tan²(88°) = 1/(x/y)²
→ tan²(88°) = y²/x²
Hence, the answer is
