((sin(θ))/(2cos(θ)))-1=0

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

θ = 1.10714 \dots + πn

Solution steps

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

Rewrite using trig identities

\frac{tan ( θ )}{2} - 1 = 0

Move

1

to the right side

\frac{tan ( θ )}{2} = 1

Multiply both sides by

2

tan (θ) = 2

Apply trig inverse properties

θ = arctan (2) + πn

Show solutions in decimal form

θ = 1.10714 \dots + πn

2 \cdot cos^{2} (2 x) + 9 \cdot cos (4 x) = - 2.4214900000000 \dots

tan (- x) = tan (x)

6 sin (θ) = 6 sin (2 θ)

2 sin (1 5^{\circ}) cos (1 5^{\circ}) = tan (x)

6 sin^{2} (x) + 5 cos (x) = 7
