sin^5(3x^2+2)=0.35

해법

sin^{5} (3 x^{2} + 2) = 0.35

해법

x = \frac{0.94519 \dots + 2 πn - 2}{3}, x = - \frac{0.94519 \dots + 2 πn - 2}{3}, x = \frac{π - 0.94519 \dots + 2 πn - 2}{3}, x = - \frac{π - 0.94519 \dots + 2 πn - 2}{3}

x = 0^{\circ} + 75.63899 \dots^{\circ} n, x = 0^{\circ} - 75.63899 \dots^{\circ} n, x = 0^{\circ} + 84.20452 \dots^{\circ} n, x = 0^{\circ} - 84.20452 \dots^{\circ} n

솔루션 단계

sin^{5} (3 x^{2} + 2) = 0.35

위해서

x^{n} = f (a)

, n은 이상하다, 해결책은

x = n f (a)

sin (3 x^{2} + 2) = 5 0.35

트리거 역속성 적용

sin (3 x^{2} + 2) = 5 0.35

일반 솔루션

sin (3 x^{2} + 2) = 5 0.35

sin (x) = a \Rightarrow x = arcsin (a) + 2 πn, x = π - arcsin (a) + 2 πn

3 x^{2} + 2 = arcsin (5 0.35) + 2 πn, 3 x^{2} + 2 = π - arcsin (5 0.35) + 2 πn

3 x^{2} + 2 = arcsin (5 0.35) + 2 πn, 3 x^{2} + 2 = π - arcsin (5 0.35) + 2 πn

3 x^{2} + 2 = arcsin (5 0.35) + 2 πn

해결 :

x = \frac{arcsin ( 5 0.35 ) + 2 πn - 2}{3}, x = - \frac{arcsin ( 5 0.35 ) + 2 πn - 2}{3}

3 x^{2} + 2 = arcsin (5 0.35) + 2 πn
