4sin(3θ)=7cos(3θ),0<= 3θ<720

4 sin (3 θ) = 7 cos (3 θ), 0^{\circ} \leq 3 θ < 72 0^{\circ}

No Solution for θ \in R

Solution steps

4 sin (3 θ) = 7 cos (3 θ), 0^{\circ} \leq 3 θ < 72 0^{\circ}

Rewrite using trig identities

4 tan (3 θ) = 7

Divide both sides by

4

tan (3 θ) = \frac{7}{4}

Apply trig inverse properties

3 θ = arctan (\frac{7}{4}) + 18 0^{\circ} n

Solve

3 θ = arctan (\frac{7}{4}) + 18 0^{\circ} n : θ = \frac{arctan ( \frac{7}{4} )}{3} + \frac{18 0 ^{\circ} n}{3}

θ = \frac{arctan ( \frac{7}{4} )}{3} + \frac{18 0 ^{\circ} n}{3}

Solutions for the range

0 \leq 3 θ < 72 0^{\circ}

No Solution for θ \in R

cot (θ) = 4

2 sin (\frac{1}{2} x) + 3 = 0

0 = - \frac{1}{7} cos (7 t)

cos (α) = \frac{5}{13}

tan (x) = 3, 0 \leq x \leq 2 π
