Solución

(4 + tan (x)) (3 sin (x) - 2) = 0

x = - 1.32581 \dots + πn, x = 0.72972 \dots + 2 πn, x = π - 0.72972 \dots + 2 πn

Pasos de solución

(4 + tan (x)) (3 sin (x) - 2) = 0

Resolver cada parte por separado

4 + tan (x) = 0 or 3 sin (x) - 2 = 0

4 + tan (x) = 0 : x = arctan (- 4) + πn

3 sin (x) - 2 = 0 : x = arcsin (\frac{2}{3}) + 2 πn, x = π - arcsin (\frac{2}{3}) + 2 πn
