cos(x)=0.7597

解

cos (x) = 0.7597

x = 0.70794 \dots + 2 πn, x = 2 π - 0.70794 \dots + 2 πn

度

x = 40.56224 \dots^{\circ} + 36 0^{\circ} n, x = 319.43775 \dots^{\circ} + 36 0^{\circ} n

解答ステップ

cos (x) = 0.7597

三角関数の逆数プロパティを適用する

cos (x) = 0.7597

以下の一般解

cos (x) = 0.7597

cos (x) = a \Rightarrow x = arccos (a) + 2 πn, x = 2 π - arccos (a) + 2 πn

x = arccos (0.7597) + 2 πn, x = 2 π - arccos (0.7597) + 2 πn

x = arccos (0.7597) + 2 πn, x = 2 π - arccos (0.7597) + 2 πn

10進法形式で解を証明する

x = 0.70794 \dots + 2 πn, x = 2 π - 0.70794 \dots + 2 πn
