-4cos(3x)=0

Solution

- 4 cos (3 x) = 0

Solution

x = \frac{π}{6} + \frac{2 πn}{3}, x = \frac{π}{2} + \frac{2 πn}{3}

+1

Solution steps

- 4 cos (3 x) = 0

Divide both sides by

- 4

cos (3 x) = 0

General solutions for

cos (3 x) = 0

3 x = \frac{π}{2} + 2 πn, 3 x = \frac{3 π}{2} + 2 πn

Solve

3 x = \frac{π}{2} + 2 πn : x = \frac{π}{6} + \frac{2 πn}{3}

Solve

3 x = \frac{3 π}{2} + 2 πn : x = \frac{π}{2} + \frac{2 πn}{3}

x = \frac{π}{6} + \frac{2 πn}{3}, x = \frac{π}{2} + \frac{2 πn}{3}

Popular Examples

(sin(40))/8 =(sin(65.38))/(sin(x))

\frac{sin ( 4 0 ^{\circ} )}{8} = \frac{sin ( 65.3 8 ^{\circ} )}{sin ( x )}

cos(28pi+x)= 1/2

cos (28 π + x) = \frac{1}{2}

1-tan^2(x)=(cos^2(x))/(cos^2(x))

1 - tan^{2} (x) = \frac{cos ^{2} ( x )}{cos ^{2} ( x )}

-2=-2sec(x)+tan^2(x)

- 2 = - 2 sec (x) + tan^{2} (x)

tan^2(y)+1=cos^2(y)

tan^{2} (y) + 1 = cos^{2} (y)
