Part 1 of 2 Solve, finding all solutions in \( [0,2 \pi) \) or \( \left[0^{\circ}, 360^{\circ}\right) \). \( 8 \cos ^{2} x=2 \) The solution(s) in \( \left[0^{\circ}, 360^{\circ}\right) \) is/are \( x=\square \). (Type your answer in degrees. Do not include the degree symbol in your answer. Use a comma separate answers as needed.)

a) Решите уравнение \( |\cos x+\sin x|=\sqrt{2} \sin 2 x \). б) Найдите решения уравнения, принадлежащи отрезку \( [3 ; 5] \).

what is the numerical value of the empression below? \( \tan ^{2} 15^{\circ}-\cot ^{2} 15^{\circ} \)

In a right triangle, if the angle A has a cotangent value of 3/4, what is the ratio of the length of the adjacent side to the length of the opposite side?

\( \frac { \operatorname { Csc } ^ { 4 } \theta - 1 } { \operatorname { Cot } ^ { 2 } \theta } = 2 + \operatorname { Cot } ^ { 2 } \theta \)

1. Given that since \( =3 / 5.0^{\circ}<x \) \( 90^{\circ} \), find the value of \( 5 \cos x- \) \( 4 \tan x \)
