critical cos(5x),0<= x<= 2pi

解

臨界点

cos (5 x), 0 \leq x \leq 2 π

解

x = 0, x = \frac{π}{5}, x = \frac{2 π}{5}, x = \frac{3 π}{5}, x = \frac{4 π}{5}, x = π, x = \frac{6 π}{5}, x = \frac{7 π}{5}, x = \frac{8 π}{5}, x = \frac{9 π}{5}, x = 2 π

解答ステップ

cos (5 x), 0 \leq x \leq 2 π

f^{'} (x)

がゼロに等しいか未定義なのはどこか見つける

x = \frac{π}{5}, x = \frac{2 π}{5}, x = \frac{3 π}{5}, x = \frac{4 π}{5}, x = π, x = \frac{6 π}{5}, x = \frac{7 π}{5}, x = \frac{8 π}{5}, x = \frac{9 π}{5}

f (x)

領域にない臨界点を特定する

以下の領域:

cos (5 x), 0 \leq x \leq 2 π : 0 \leq x \leq 2 π

あらゆる臨界点は領域内にある

x = \frac{π}{5}, x = \frac{2 π}{5}, x = \frac{3 π}{5}, x = \frac{4 π}{5}, x = π, x = \frac{6 π}{5}, x = \frac{7 π}{5}, x = \frac{8 π}{5}, x = \frac{9 π}{5}
