2sin(θ)-cos(θ)=0

2 sin (θ) - cos (θ) = 0

θ = 0.46364 \dots + πn

Solution steps

2 sin (θ) - cos (θ) = 0

Rewrite using trig identities

2 tan (θ) - 1 = 0

Move

1

to the right side

2 tan (θ) = 1

Divide both sides by

2

tan (θ) = \frac{1}{2}

Apply trig inverse properties

θ = arctan (\frac{1}{2}) + πn

Show solutions in decimal form

θ = 0.46364 \dots + πn

cot (\frac{x}{7}) = 12

sin (θ) = \frac{4}{9}

y, x = sec (y)

2 cos^{2} (θ) - cos (θ) - 4 = - 6 cos (θ) - 6

sin (x) + 2 cos (x) = 1
