練習29教えてほしいです🙇

6 第2章 複素数と方程式 3乗するとαになる数をαの3乗根という。 すなわち, x = α と なる数xがαの3乗根である。 前ページ例17 より,1の3乗根は, -1+√3-1-√3i 練習 29 1, 2 9 2 である。 オメガ 1の3乗根のうち虚数であるものの1つをω とするとき,次のこと を示せ。 (1) 1の3乗根は 1 2 である。 (2) w²+w+1=0 工夫して因数分解することで, 高次方程式を解いてみよう。 例 4次方程式xx-2=0 を解く。 18 左辺を因数分解すると (x-2)(x2+1)=0 よって x2-2 = 0 またはx+1=0 ← (x²)²-x²-2=0

He said, 「 11 I told the witch that I would give you the life cr 11 of the next person who visited you for 10 years." (55

4倍振動 というのはどこから分かりますか？

149 弦の振動 ② 弦の一端におもりを取り付け, 他端にスピーカーを取り付けた。 右図のように, ス ピーカーから 3.0mのところに滑らかな滑車がくる ようにし, スピーカーの振動数を25Hzに調整した ところ, 弦にはP, Q を節とする3倍振動が現れた。 (1) 弦を伝わる波の波長は何mか。 (2) 弦を伝わる波の速さは何m/sか。 (3) 弦の状態はそのままで, スピーカーの振動数を上げていく。 次に, 弦が共振する スピーカーの振動数は何Hzか｡ 解説を見る 55 D.V (3) 図2より, 波長 X', 図2 λ' X' 2 ×4 = 3.0 よって, X' = 1.5m v=fx より 求める 振動数 f' は, f' = UV TEVG = V 50 X' 1.5 33.3... 3.0m P スピーカー 3倍振動が基本振動の3倍の振動 数であるので、基本振動の振動数 は, Hz とわかる。 25 3 求めるのは, 4倍振動の振動数な ので, 25 -X133 3... = 32 Hz 3.0 m おもり

3番のこのグラフの書き換えが全く分からないので教えてください

分析 140 波のグラフ (y-tグラフ) 右図は,x 作図 軸を速さ2.0cm/sで正の向きに進む正弦波の 47 x=0cmの点の変位y [cm〕 と時刻t [s] の関係 をグラフに表したものである。 (1) この波の周期を求めよ。 (2) この波の振動数と波長を求めよ。 (3) この波のt= 0sにおける波形を 0cm≦x≦10cmの範囲で描け。 解説を見る (3) y-tグラフより, t = 0s の とき x=0cmの点はy=0cm である。 また、その後、時間 が経過すると, x=0cmの点 はy軸正の向きに変位するの -1.0 で, x=0cmの点の付近のx 軸負の領域には, 波の山があ ると決定できる。 よって右図 otak7 to 2 1.04y[cm] 10/20 4.0/ 10 x[cm] 8.0 y[cm〕 1.0 -1.0 2.0 14.0 -t[s]
