Question

The value of determinant `|(sin^2 13°, sin^2 77°, tan135°),(sin^2 77°, tan135°, sin^2 13°),(tan135°, sin^2 13°, sin^2 77°)|` is

Answer 1

0

Explanation:

`|(sin^2 13°, cos^2 13°, -1),(cos^2 13°, -1, sin^2 13°),(-1, sin^2 13°, cos^2 13°)|`

= `|(0, cos^2 13°, -1),(0, -1, sin^2 13°),(0, sin^2 13°, cos^2 13°)|`

= 0

Applying C₁ → C₁ + C₂ + C₃
