-2sin(x)-2+4sin^2(x)=0

Solution

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

Solution

x = \frac{π}{2} + 2 πn, x = \frac{7 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

+1

Solution steps

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

Solve by substitution

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

sin (x) = 1 : x = \frac{π}{2} + 2 πn

sin (x) = - \frac{1}{2} : x = \frac{7 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

Combine all the solutions

x = \frac{π}{2} + 2 πn, x = \frac{7 π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

Popular Examples

cos(x)=-3/5 ,pi<x<(3pi)/2 ,sin(x/2)

cos (x) = - \frac{3}{5}, π < x < \frac{3 π}{2}, sin (\frac{x}{2})

30=arccos(6/(x(3)))

3 0^{\circ} = arccos (\frac{6}{x ( 3 )})

sin(θ)=0.18421

sin (θ) = 0.18421

6/(3tan(θ)+1)=5

\frac{6}{3 tan ( θ ) + 1} = 5

cos(x)=2-3sin(x)

cos (x) = 2 - 3 sin (x)
