29cos(x)=-17-cos(x)

29 cos (x) = - 17 - cos (x)

x = 2.17325 \dots + 2 πn, x = - 2.17325 \dots + 2 πn

Solution steps

29 cos (x) = - 17 - cos (x)

Solve by substitution

cos (x) = - \frac{17}{30}

cos (x) = - \frac{17}{30} : x = arccos (- \frac{17}{30}) + 2 πn, x = - arccos (- \frac{17}{30}) + 2 πn

Combine all the solutions

x = arccos (- \frac{17}{30}) + 2 πn, x = - arccos (- \frac{17}{30}) + 2 πn

Show solutions in decimal form

x = 2.17325 \dots + 2 πn, x = - 2.17325 \dots + 2 πn

2 cos (x) + 2 cos (2 x) = 0

cos^{2} (x) + sin (x) = 0

tan (x) = \frac{- 3}{3}

tan (\frac{x}{3}) = \frac{3}{3}

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