3 θ = 27 0^{\circ} + 36 0^{\circ} n

3 θ = 27 0^{\circ} + 36 0^{\circ} n

Solve

3 θ = 27 0^{\circ} + 36 0^{\circ} n : θ = 9 0^{\circ} + \frac{36 0 ^{\circ} n}{3}

3 θ = 27 0^{\circ} + 36 0^{\circ} n

Divide both sides by

3

3 θ = 27 0^{\circ} + 36 0^{\circ} n

Divide both sides by

3

\frac{3 θ}{3} = \frac{27 0 ^{\circ}}{3} + \frac{36 0 ^{\circ} n}{3}

Simplify

\frac{3 θ}{3} = \frac{27 0 ^{\circ}}{3} + \frac{36 0 ^{\circ} n}{3}

Simplify

\frac{3 θ}{3} : θ

\frac{3 θ}{3}

Divide the numbers:

\frac{3}{3} = 1

= θ

Simplify

\frac{27 0 ^{\circ}}{3} + \frac{36 0 ^{\circ} n}{3} : 9 0^{\circ} + \frac{36 0 ^{\circ} n}{3}

\frac{27 0 ^{\circ}}{3} + \frac{36 0 ^{\circ} n}{3}

\frac{27 0 ^{\circ}}{3} = 9 0^{\circ}

\frac{27 0 ^{\circ}}{3}

Apply the fraction rule:

\frac{\frac{b}{c}}{a} = \frac{b}{c \cdot a}

= \frac{54 0 ^{\circ}}{2 \cdot 3}

Multiply the numbers:

2 \cdot 3 = 6

= 9 0^{\circ}

Cancel the common factor:

3

= 9 0^{\circ}

= 9 0^{\circ} + \frac{36 0 ^{\circ} n}{3}

θ = 9 0^{\circ} + \frac{36 0 ^{\circ} n}{3}

θ = 9 0^{\circ} + \frac{36 0 ^{\circ} n}{3}

θ = 9 0^{\circ} + \frac{36 0 ^{\circ} n}{3}

θ = 9 0^{\circ} + \frac{36 0 ^{\circ} n}{3}

Solutions for the range

0 \leq θ \leq 36 0^{\circ}

θ = 9 0^{\circ}, θ = 21 0^{\circ}, θ = 33 0^{\circ}

3 csc^{2} (x) + cot^{2} (x) - 4 = 0

θ, x = 2 sec (θ)

3 sec (3 x) = - 2

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

tan (x) = \frac{1}{0}
