cos(x)=a

cos (x) = a

x = arccos (a) + 2 πn, x = - arccos (a) + 2 πn

Solution steps

cos (x) = a

Apply trig inverse properties

cos (x) = a

General solutions for

cos (x) = a

cos (x) = a \Rightarrow x = arccos (a) + 2 πn, x = - arccos (a) + 2 πn

x = arccos (a) + 2 πn, x = - arccos (a) + 2 πn

x = arccos (a) + 2 πn, x = - arccos (a) + 2 πn

cos (4 w) = 0

(2 sin (x) + 5) (3 cos (x) + 3) (tan^{2} (x) - 2) = 0

3 sin (x) + 3 cos (2 x) = 2

tan (3 x + 2 5^{\circ}) \cdot 16 0^{\circ} - 1 = 0

5 cos (x) = 1
