cos(a)= 3/3

cos (a) = \frac{3}{3}

a = 2 πn

Degrees

a = 0^{\circ} + 36 0^{\circ} n

Solution steps

cos (a) = \frac{3}{3}

Apply rule

\frac{a}{a} = 1

cos (a) = 1

General solutions for

cos (a) = 1

a = 0 + 2 πn

a = 0 + 2 πn

Solve

a = 0 + 2 πn : a = 2 πn

a = 0 + 2 πn

0 + 2 πn = 2 πn

a = 2 πn

a = 2 πn

3 csc^{2} (x) - 2 csc (x) - 5 = 0

cos (2 x - 1) = 0.4

cos (3 x) cos (x) = 2 cos (2 x) cos (x)

0 = cos (2 x) - cos (x)

cos (θ) = 0.6015
