2tan^2(x)+tan(x)=0

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

x = πn, x = - 0.46364 \dots + πn

Solution steps

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

Solve by substitution

tan (x) = 0, tan (x) = - \frac{1}{2}

tan (x) = 0 : x = πn

tan (x) = - \frac{1}{2} : x = arctan (- \frac{1}{2}) + πn

Combine all the solutions

x = πn, x = arctan (- \frac{1}{2}) + πn

Show solutions in decimal form

x = πn, x = - 0.46364 \dots + πn

2 sin (2 x) = 3

sin (θ) = \frac{4}{5}, cos (2 θ), 90 \leq θ < 180

2 cos (x) = 1, 0, 36 0^{\circ}

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

16 sin^{4} (θ) - 16 sin^{2} (θ) + 3 = 0
