数学Ⅲ 積分法の問題です （1）の問題で答えを求めるのにグラフを書く必要があると思うんですけど、3次関数のグラフの概形をなるべく早く、正確に書く方法を教えてほしいです🙇‍♂️

その式で 295. 次の曲線や直線で囲まれた2つの部分の面積の和Sを求めよ。 □ (1) y=-x+3x2-4, y=x-x-2 30 (2)* y=log (1-x), y 軸, y=-2,y=1 □ (3) * y=sinx, y=cos2x (0≦x≦2) mの値を定め

角度がπを使ったの形での場合半角の公式を使ってどうやって求められますか？解説お願いします🙏

461 半角の公式を用いて, 次の値を求めよ。 (1) sin π 12 5 *(2) cos π 8 (3) tan- 38 8π 第4章

θの範囲に制限がない時、sinθとcosθは2nπと解答が書いてあるのに、tanθがnπになるのはなんでですか？解説お願いします😭

*4440≦02 のとき,次の方程式を解け。 また, 0 の範囲に制限 がないときはどうか。 1 (1) sin0= √2 1 1 (2) cos=- (3) tan0= 2

数2Bの加法定理の所なんですけど、ここの問題分からなくて😭😭丁寧に解説して頂きたいです😿‪

1 156 sina+cosẞ=- 2' cosa+sinẞ=*, sin(a+ß) の値を求めよ。 π α-B= α-β= のとき, (tan+1)(tanβ-1) の値を求めよ。

なぜcouldにはならないのですか？
