求解這倆題~

1. tan(cos¹ (2/5)) 2. sin(tan¹(x))

想問勝算比我寫的為什麼跟答案的算法不一樣？是理解錯誤嗎

習題2.8 計算並解釋樣本勝算比、相對危險、比例差, 說明為何勝算比近似相對危險 傷害 P1F 安全裝置 致命 非致命 n11 = nit 121 - n2+ 1601 =0.01 164128 510 =0.001 412878 未使用 1601 P2 162,527 412,368 安全帶 510 勝算A_Ti/(1-T1) 勝算比 = 勝算B T2/(1-T2) - - = 0.01/(1-0.01) -- 10.102 0.001/(1-0.001) 表示未使用致死勝算是安全带致死勝算的10.102倍

哪個微積分大神幫我看一下這證明可不可以！ 又或是我可以從哪裡著手呢？~

5. 某批零件尺寸呈 N100, 196)之常態分配,则P[86SX S142]為何? (10%) 註:標準常態分配之累積函数值F(z)如下:F(0.00)=0.5000, F(1.00) = 0.8413. F(2.00) = 0.9772. F(3.00) = 0.9987 6.假設混凝土允許任何連續三组強度試驗結果之平均值小於規定強度fc {fc' =210 kgf/cm?〉之機率為1%,該批混凝土強度之標準差為15 kgf/cm?, 則目標平均強度fcr'為何?(15%) 註:標準常態分配之累積函数值F(x)如下:F(0.00)=0.500,F(1.00) = 0.8413,F(2.00)=0.9772,F(2.33)=0.9901 註:我國鋼筋混凝土規範大多參考美國混凝土學會ACI-318鋼筋混凝土設計規 範,設定允許發生不符合機率為1%。

有人可以解釋一下箭頭畫的地方是怎麼來的嗎？我知道目標是要把1-sin^2θ換成cos^2θ

985 Double Integrals and Volume EXAMPLE 5 14.2 Volume of a Region Bounded by Two Surfaces Find the volume of the solid region bounded above by the paraboloid Paraboloid z = 1 - x2 - y2 and below by the plane z = 1- y as shown in Figure 14.20. Plane Paraboloid: z=1 - x2 - y2 Plane: z=1-y Figure 14.20 Solution Equating z-values, you can determine that the intersection of the two surfaces occurs on the right circular cylinder given by 1- y = 1 - x2 - y2 x² = y - y². So, the region R in the xy-plane is a circle, as shown in Figure 14.21. Because the volume of the solid region is the difference between the volume under the paraboloid and the volume under the plane, you have Volume = (volume under paraboloid) – (volume under plane) Wyz?
