cos^{(2)}(x)+2cos(x)=3

cos^{(2)} (x) + 2 cos (x) = 3

x = 2 πn

Solution steps

cos^{(2)} (x) + 2 cos (x) = 3

Solve by substitution

cos (x) = 1, cos (x) = - 3

cos (x) = 1 : x = 2 πn

cos (x) = - 3 :

x = 2 πn

cos (A) = \frac{1 ^{2} + 5. 2 ^{2} - 3.5}{2 ( 1 ) ( 5.2 )}

cos (5 x) - cos (3 x) = sin (4 x)

cos (9 0^{\circ} - x) + csc (x) = \frac{5}{2}

x, sin (x) - csc (t) + 1 = 0

cos^{2} (x) = \frac{3}{4 \cdot 5 cos ^{2} ( x )}
