12cot^2(x)=4

Solution

12 cot^{2} (x) = 4

Solution

x = 1.04719 \dots + πn, x = 2.09439 \dots + πn

+1

Solution steps

12 cot^{2} (x) = 4

Solve by substitution

cot (x) = \frac{1}{3}, cot (x) = - \frac{1}{3}

cot (x) = \frac{1}{3} : x = arccot (\frac{1}{3}) + πn

cot (x) = - \frac{1}{3} : x = arccot (- \frac{1}{3}) + πn

Combine all the solutions

x = arccot (\frac{1}{3}) + πn, x = arccot (- \frac{1}{3}) + πn

Show solutions in decimal form

x = 1.04719 \dots + πn, x = 2.09439 \dots + πn

Popular Examples

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

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

5sin^2(θ)+2sin(θ)=0

5 sin^{2} (θ) + 2 sin (θ) = 0

cos(θ)cos(3θ)-sin(θ)sin(3θ)=0

cos (θ) cos (3 θ) - sin (θ) sin (3 θ) = 0

1-2sin(θ)=cos(2θ),0<= θ<= 2pi

1 - 2 sin (θ) = cos (2 θ), 0 \leq θ \leq 2 π

2sin^2(θ)+5sin(θ)-12=0

2 sin^{2} (θ) + 5 sin (θ) - 12 = 0
