Question

`sqrt(3)` cos²A + `sqrt(3)` sin²A is equal to ______.

विकल्प

• 1

• `1/sqrt(3)`

• `sqrt(3)`

• 0

Answer 1

`sqrt(3)` cos²A + `sqrt(3)` sin²A is equal to `underline(bbsqrt(3))`.

Explanation:

`sqrt(3)` cos²A + `sqrt(3)` sin²A

`sqrt(3)  ((cos^2A + sin^2A))/(cos^2A + sin^2A)` = 1

`sqrt(3) xx 1 = sqrt(3)`
