Question

Guyssss can u solve it?
​

Answer 1

Answer :- 1

Solution :-

Break the determinant 1st

so, we get after break determint is as fellow

= Sin10° × cos80° + sin80° cos10°

= sin10° cos ( 90° -10) + sin(90°-10)cos10°

= sin10° *sin10° + cos10° *cos10°

= sin²10° + cos²10°

As we know , sin²¢ + cos²¢ = 1

since, 1 Answer ..
