1-3cos(x)=0

1 - 3 cos (x) = 0

x = 1.23095 \dots + 2 πn, x = 2 π - 1.23095 \dots + 2 πn

Solution steps

1 - 3 cos (x) = 0

Move

1

to the right side

- 3 cos (x) = - 1

Divide both sides by

- 3

cos (x) = \frac{1}{3}

Apply trig inverse properties

x = arccos (\frac{1}{3}) + 2 πn, x = 2 π - arccos (\frac{1}{3}) + 2 πn

Show solutions in decimal form

x = 1.23095 \dots + 2 πn, x = 2 π - 1.23095 \dots + 2 πn

- sin (x) + 2 sin (2 x) = 0

arccos (x) = arcsin (\frac{3}{5})

x, y = 2 tan (x)

sin^{2} (x) - cos^{2} (x) - 1 = 0

tan (x) - 1 = - \frac{1}{3} + \frac{1}{3} cot (x)
