受欢迎的三角函数 >

sin(θ)= 7/12

解答

sin (θ) = \frac{7}{12}

解答

θ = 0.62282 \dots + 2 πn, θ = π - 0.62282 \dots + 2 πn

+1

度数

θ = 35.68533 \dots^{\circ} + 36 0^{\circ} n, θ = 144.31466 \dots^{\circ} + 36 0^{\circ} n

求解步骤

sin (θ) = \frac{7}{12}

使用反三角函数性质

sin (θ) = \frac{7}{12}

sin (θ) = \frac{7}{12}

的通解

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

θ = arcsin (\frac{7}{12}) + 2 πn, θ = π - arcsin (\frac{7}{12}) + 2 πn

θ = arcsin (\frac{7}{12}) + 2 πn, θ = π - arcsin (\frac{7}{12}) + 2 πn

以小数形式表示解

θ = 0.62282 \dots + 2 πn, θ = π - 0.62282 \dots + 2 πn

3cos(2x)+2sin^2(x)=2

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

solvefor x,cos(3x)=1

so l v e f or x, cos (3 x) = 1

sec(x)+tan(x)=2

sec (x) + tan (x) = 2

cos (A) = - \frac{1}{2}

sin (x) = cos (4 x)
