solvefor 3cot^2(x)-1=0,x

solve for

3 cot^{2} (x) - 1 = 0, x

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

Solution steps

3 cot^{2} (x) - 1 = 0

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

cos^{2} (x) + cos (2 x) = 0

- 2 sin (θ) + 3 cos (2 θ) = 0

sin^{2} (x) - 4 = 0

tan (a) = \frac{2.8}{9}

cos (2 x) - 9 cos (x) + 5 = 0
