인기 있는 삼각법 >

(sin^{22}(a))/(sin^2(a))=4-4sin^2(a)

해법

\frac{sin ^{22} ( a )}{sin ^{2} ( a )} = 4 - 4 sin^{2} (a)

해법

a = 1.25989 \dots + 2 πn, a = π - 1.25989 \dots + 2 πn, a = - 1.25989 \dots + 2 πn, a = π + 1.25989 \dots + 2 πn

솔루션 단계

\frac{sin ^{22} ( a )}{sin ^{2} ( a )} = 4 - 4 sin^{2} (a)

대체로 해결

\frac{sin ^{22} ( a )}{sin ^{2} ( a )} = 4 - 4 sin^{2} (a)

하게:

sin (a) = u

\frac{u ^{22}}{u ^{2}} = 4 - 4 u^{2}

\frac{u ^{22}}{u ^{2}} = 4 - 4 u^{2} : u = 0.90641 \dots, u = - 0.90641 \dots

\frac{u ^{22}}{u ^{2}} = 4 - 4 u^{2}

\frac{u ^{22}}{u ^{2}}

간소화하다 :

u^{20}

\frac{u ^{22}}{u ^{2}}

지수 규칙 적용:

\frac{x ^{a}}{x ^{b}} = x^{a - b}

\frac{u ^{22}}{u ^{2}} = u^{22 - 2}

= u^{22 - 2}

숫자를 빼세요:

22 - 2 = 20

= u^{20}

u^{20} = 4 - 4 u^{2}

u^{20} = 4 - 4 u^{2}

해결 :

u = 0.90641 \dots, u = - 0.90641 \dots

u^{20} = 4 - 4 u^{2}

4 u^{2}

를 왼쪽으로 이동

u^{20} = 4 - 4 u^{2}

더하다

4 u^{2}

양쪽으로

u^{20} + 4 u^{2} = 4 - 4 u^{2} + 4 u^{2}

단순화

u^{20} + 4 u^{2} = 4

u^{20} + 4 u^{2} = 4

4

를 왼쪽으로 이동

u^{20} + 4 u^{2} = 4

빼다

양쪽에서

u^{20} + 4 u^{2} - 4 = 4 - 4

단순화

u^{20} + 4 u^{2} - 4 = 0

u^{20} + 4 u^{2} - 4 = 0

다음으로 방정식 다시 쓰기

v = u^{2}

그리고

v^{10} = u^{20}

v^{10} + 4 v - 4 = 0

v^{10} + 4 v - 4 = 0

해결 :

u = 0.90641 \dots, u = - 0.90641 \dots

u = 0.90641 \dots, u = - 0.90641 \dots

솔루션 확인

정의되지 않은 (특이점) 점 찾기:

u = 0

의 분모를 취하라

\frac{u ^{22}}{u ^{2}}

그리고 0과 비교한다

u^{2} = 0

해결 :

u = 0

u^{2} = 0

규칙 적용

x^{n} = 0 \Rightarrow x = 0

u = 0

다음 지점은 정의되지 않았습니다

u = 0

정의되지 않은 점을 솔루션과 결합:

u = 0.90641 \dots, u = - 0.90641 \dots

뒤로 대체

u = sin (a)

sin (a) = 0.90641 \dots, sin (a) = - 0.90641 \dots

sin (a) = 0.90641 \dots, sin (a) = - 0.90641 \dots

sin (a) = 0.90641 \dots : a = arcsin (0.90641 \dots) + 2 πn, a = π - arcsin (0.90641 \dots) + 2 πn

sin (a) = 0.90641 \dots

트리거 역속성 적용

sin (a) = 0.90641 \dots

일반 솔루션

sin (a) = 0.90641 \dots

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

a = arcsin (0.90641 \dots) + 2 πn, a = π - arcsin (0.90641 \dots) + 2 πn

a = arcsin (0.90641 \dots) + 2 πn, a = π - arcsin (0.90641 \dots) + 2 πn

sin (a) = - 0.90641 \dots : a = arcsin (- 0.90641 \dots) + 2 πn, a = π + arcsin (0.90641 \dots) + 2 πn

sin (a) = - 0.90641 \dots

트리거 역속성 적용

sin (a) = - 0.90641 \dots

일반 솔루션

sin (a) = - 0.90641 \dots

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

a = arcsin (- 0.90641 \dots) + 2 πn, a = π + arcsin (0.90641 \dots) + 2 πn

a = arcsin (- 0.90641 \dots) + 2 πn, a = π + arcsin (0.90641 \dots) + 2 πn

모든 솔루션 결합

a = arcsin (0.90641 \dots) + 2 πn, a = π - arcsin (0.90641 \dots) + 2 πn, a = arcsin (- 0.90641 \dots) + 2 πn, a = π + arcsin (0.90641 \dots) + 2 πn

해를 10진수 형식으로 표시

a = 1.25989 \dots + 2 πn, a = π - 1.25989 \dots + 2 πn, a = - 1.25989 \dots + 2 πn, a = π + 1.25989 \dots + 2 πn

그래프

인기 있는 예

sin^3(x)=3sin(x)

cos^4(x)+2sin^2(x)+6cos^2(x)+5=0

1+sin(2a)=sin^2(a)

((cos^3(a)))/((2cos^2(a)-1))=cos(a)
