2=2cos(pi+x)

2 = 2 cos (π + x)

x = 2 πn - π

Solution steps

2 = 2 cos (π + x)

Switch sides

2 cos (π + x) = 2

Divide both sides by

2

cos (π + x) = 1

General solutions for

cos (π + x) = 1

π + x = 0 + 2 πn

Solve

π + x = 0 + 2 πn : x = 2 πn - π

x = 2 πn - π

cot (x) + csc (x) cos (x) = 2, cot (x)

- 4 cos (3 θ) = 1

960 = 480 (1 - cos (7.5 x))

8 = 8 tan (θ)

2 sin (2 x) - 3 cos (x) = 0
