cos(x)=(1.5)/9

cos (x) = \frac{1.5}{9}

x = 1.40334 \dots + 2 πn, x = 2 π - 1.40334 \dots + 2 πn

Solution steps

cos (x) = \frac{1.5}{9}

Apply trig inverse properties

x = arccos (\frac{1.5}{9}) + 2 πn, x = 2 π - arccos (\frac{1.5}{9}) + 2 πn

Show solutions in decimal form

x = 1.40334 \dots + 2 πn, x = 2 π - 1.40334 \dots + 2 πn

sin (3 x) = \frac{2}{2}, 0 \leq x < 2 π

6 = cot^{2} (x) + 8 cot (x)

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

5 sin (x) = 2 + sin (x)

- 3 = 4 - 2 arctan (\frac{4 - 2 - C}{4 - C})
