Solution

2 cos (x) + 1 = 3

Solution

x = 2 πn

+1

Solution steps

2 cos (x) + 1 = 3

Move

1

to the right side

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

sec(x)+tan(x)=0

sec (x) + tan (x) = 0

sin(x+pi/6)-sin(x-(7pi)/6)=(sqrt(3))/2

sin (x + \frac{π}{6}) - sin (x - \frac{7 π}{6}) = \frac{3}{2}

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

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

sin(2x)+sin(x)=0,0<= x<= 2pi

sin (2 x) + sin (x) = 0, 0 \leq x \leq 2 π

cos (2 t) = 0
