cos(x)tan(x)=-7tan(x)

cos (x) tan (x) = - 7 tan (x)

x = πn

Solution steps

cos (x) tan (x) = - 7 tan (x)

Subtract

- 7 tan (x)

from both sides

cos (x) tan (x) + 7 tan (x) = 0

Factor

cos (x) tan (x) + 7 tan (x) : tan (x) (cos (x) + 7)

tan (x) (cos (x) + 7) = 0

Solving each part separately

tan (x) = 0 or cos (x) + 7 = 0

tan (x) = 0 : x = πn

cos (x) + 7 = 0 :

No Solution

Combine all the solutions

x = πn

12 sin^{2} (θ) - 9 = 0

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

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

cos (x) tan (x) + 4 tan (x) = 0

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