csc(A)=(9.43)/5

解

csc (A) = \frac{9.43}{5}

A = 0.55886 \dots + 2 πn, A = π - 0.55886 \dots + 2 πn

度

A = 32.02050 \dots^{\circ} + 36 0^{\circ} n, A = 147.97949 \dots^{\circ} + 36 0^{\circ} n

解答ステップ

csc (A) = \frac{9.43}{5}

三角関数の逆数プロパティを適用する

csc (A) = \frac{9.43}{5}

以下の一般解

csc (A) = \frac{9.43}{5}

csc (x) = a \Rightarrow x = arccsc (a) + 2 πn, x = π - arccsc (a) + 2 πn

A = arccsc (\frac{9.43}{5}) + 2 πn, A = π - arccsc (\frac{9.43}{5}) + 2 πn

A = arccsc (\frac{9.43}{5}) + 2 πn, A = π - arccsc (\frac{9.43}{5}) + 2 πn

10進法形式で解を証明する

A = 0.55886 \dots + 2 πn, A = π - 0.55886 \dots + 2 πn
