The value of sec2600cos2450+cosec2300sec2450−tan450{{sec^260⁰cos^245⁰+cosec^230⁰} \over sec^245⁰-tan45⁰}?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 6 .

Given, sec2600cos2450+cosec2300sec2450−tan450{{sec^260⁰cos^245⁰+cosec^230⁰} \over sec^245⁰-tan45⁰}

⇒ 4×(12)+42−1\frac{4 \times (\frac{1}{2}) + 4}{2 - 1} 

⇒ 6/1 = 6
