2tan(x)+2=0

2 tan (x) + 2 = 0

x = \frac{3 π}{4} + πn

Degrees

x = 13 5^{\circ} + 18 0^{\circ} n

Solution steps

2 tan (x) + 2 = 0

Move

2

to the right side

2 tan (x) + 2 = 0

Subtract

2

from both sides

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

Simplify

2 tan (x) = - 2

2 tan (x) = - 2

Divide both sides by

2

2 tan (x) = - 2

Divide both sides by

2

\frac{2 tan ( x )}{2} = \frac{- 2}{2}

Simplify

tan (x) = - 1

tan (x) = - 1

0 = sin (2 x)

2 cos^{2} (x) - 3 cos (x) - 2 = 0

sin (2 x) csc (2 x) - 2 sin (2 x) = 0

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