Question

the value of x for the maximum value of root 3 cos x + sin x is what​

Answer 1

The maximum value of cos X is 1

the maximum value of sin X is 1

$\sqrt{3 \cos(x) + \sin(x) } \\ = \sqrt{3 \times 1 + 1} \\ = \sqrt{3 + 1} \\ = \sqrt{4 } \\ = 2 \: \: \: \: \: \: or \: \: \: \: \: \: - 2$

we need only the maximum value so.

it will be. 2
