7 cos (3 x) = 7

Divide both sides by

7

cos (3 x) = 1

General solutions for

cos (3 x) = 1

3 x = 0 + 2 πn

Solve

3 x = 0 + 2 πn : x = \frac{2 πn}{3}

x = \frac{2 πn}{3}

Popular Examples

cos^2(θ)=sin^2(θ)+1

cos^{2} (θ) = sin^{2} (θ) + 1

sin(x+pi/4)+sin(x-pi/4)-1=0

sin (x + \frac{π}{4}) + sin (x - \frac{π}{4}) - 1 = 0

1/2 sin(x)=-(sqrt(3))/4

\frac{1}{2} sin (x) = - \frac{3}{4}

cos^2(x)+3cos(x)-4=0

cos^{2} (x) + 3 cos (x) - 4 = 0

7sin(x)=cos(x)-3

7 sin (x) = cos (x) - 3
