Question

16cotA=12 find the value of sinA+cosA/sinA-cosA

Answer 1

Hope u understand everything

Answer 2

multiplying and dividing (sinA + cosA)/(sinA - cosA) with CosA

we get (tanA + 1)/(tanA - 1)

given that cotA = 3/4 ⇒ tanA = 4/3

substituting the value of tanA in the derived expression we get

⇒ (4/3 + 1)/(4/3 - 1) = 7
