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

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

x = \frac{π}{6} + 2 πn, x = \frac{5 π}{6} + 2 πn

Degrees

x = 3 0^{\circ} + 36 0^{\circ} n, x = 15 0^{\circ} + 36 0^{\circ} n

Solution steps

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

Factor

tan (x) csc (x) - 2 tan (x) : tan (x) (csc (x) - 2)

tan (x) csc (x) - 2 tan (x)

Factor out common term

tan (x)

= tan (x) (csc (x) - 2)

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

Solving each part separately

tan (x) = 0 or csc (x) - 2 = 0

tan (x) = 0 : x = πn

tan (x) = 0

cycle:

x 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} \frac{π}{2} \frac{2 π}{3} \frac{3 π}{4} \frac{5 π}{6} tan (x) 0 \frac{3}{3} 13 \pm \infty - 3 - 1 - \frac{3}{3}

x = 0 + πn

x = 0 + πn

Solve

x = 0 + πn : x = πn

x = 0 + πn

0 + πn = πn

x = πn

x = πn

csc (x) - 2 = 0 : x = \frac{π}{6} + 2 πn, x = \frac{5 π}{6} + 2 πn

csc (x) - 2 = 0

Move

2

to the right side

csc (x) - 2 = 0

Add

2

to both sides

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

Simplify

csc (x) = 2

csc (x) = 2

x = \frac{π}{6} + 2 πn, x = \frac{5 π}{6} + 2 πn

x = \frac{π}{6} + 2 πn, x = \frac{5 π}{6} + 2 πn

Combine all the solutions

x = πn, x = \frac{π}{6} + 2 πn, x = \frac{5 π}{6} + 2 πn

Since the equation is undefined for:

πn

x = \frac{π}{6} + 2 πn, x = \frac{5 π}{6} + 2 πn

1 - 2 sin (θ) = 0

cos (2 θ) + 3 cos (θ) = 4

0 = 2 cos (x) - 3 sin (x)

- cos (x) - sin (x) = 0

sin (x) = - \frac{1}{6}
