0.26=sin(0.25pit)

解

0.26 = sin (0.25 π t)

解

t = \frac{0.26302 \dots}{0.25 π} + \frac{2 n}{0.25}, t = \frac{1}{0.25} - \frac{0.26302 \dots}{0.25 π} + \frac{2 n}{0.25}

度

t = 19.18779 \dots^{\circ} + 458.36623 \dots^{\circ} n, t = 209.99531 \dots^{\circ} + 458.36623 \dots^{\circ} n

解答ステップ

0.26 = sin (0.25 π t)

辺を交換する

sin (0.25 π t) = 0.26

三角関数の逆数プロパティを適用する

sin (0.25 π t) = 0.26

以下の一般解

sin (0.25 π t) = 0.26

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

0.25 π t = arcsin (0.26) + 2 πn, 0.25 π t = π - arcsin (0.26) + 2 πn

0.25 π t = arcsin (0.26) + 2 πn, 0.25 π t = π - arcsin (0.26) + 2 πn

解く

0.25 π t = arcsin (0.26) + 2 πn : t = \frac{arcsin ( 0.26 )}{0.25 π} + \frac{2 n}{0.25}

0.25 π t = arcsin (0.26) + 2 πn

以下で両辺を割る

0.25 π

0.25 π t = arcsin (0.26) + 2 πn

以下で両辺を割る

0.25 π

\frac{0.25 π t}{0.25 π} = \frac{arcsin ( 0.26 )}{0.25 π} + \frac{2 πn}{0.25 π}

簡素化

t = \frac{arcsin ( 0.26 )}{0.25 π} + \frac{2 n}{0.25}

t = \frac{arcsin ( 0.26 )}{0.25 π} + \frac{2 n}{0.25}

解く

0.25 π t = π - arcsin (0.26) + 2 πn : t = \frac{1}{0.25} - \frac{arcsin ( 0.26 )}{0.25 π} + \frac{2 n}{0.25}

0.25 π t = π - arcsin (0.26) + 2 πn

以下で両辺を割る

0.25 π

0.25 π t = π - arcsin (0.26) + 2 πn

以下で両辺を割る

0.25 π

\frac{0.25 π t}{0.25 π} = \frac{π}{0.25 π} - \frac{arcsin ( 0.26 )}{0.25 π} + \frac{2 πn}{0.25 π}

簡素化

\frac{0.25 π t}{0.25 π} = \frac{π}{0.25 π} - \frac{arcsin ( 0.26 )}{0.25 π} + \frac{2 πn}{0.25 π}
