Solution

2 cos (x) = 2

Solution

x = 2 πn

+1

Solution steps

2 cos (x) = 2

Divide both sides by

2

cos (x) = 1

General solutions for

cos (x) = 1

x = 0 + 2 πn

Solve

x = 0 + 2 πn : x = 2 πn

x = 2 πn

Popular Examples

sin(2θ)=sqrt(3)sin(θ)

sin (2 θ) = 3 sin (θ)

cot (\frac{x}{2}) = 1

-8tan^2(θ)-4tan(θ)-11=6tan(θ)-8

- 8 tan^{2} (θ) - 4 tan (θ) - 11 = 6 tan (θ) - 8

2cos^2(x)+3cos(x)-5=0

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

1+cos^2(x)=sin^2(x)

1 + cos^{2} (x) = sin^{2} (x)
