求解🙏 答案：（15）（-極限，-2）U（-2，極限） （16）（k,k+1),k為任意整數 （17）（-極限，1）U（1，極限） （18）（-極限，2）U（2，極限）

寫出下列 各函數在其上連續的區間。

請問這題為什麼只能先對y積分？只是因為先對x的話積不出來嗎？

Evaluate the double integral: f(x, y) = ye; R is bounded by x=2 2 and y=0. ud hisborod【107 東吳巨資】 解:積分區域R如圖,只能先對 y 積分 s!

求解這題的計算過程 我分部積分積不出來 答案是0.6109 。

5.2. A group of construction workers take time X (in hours) to finish a task. The density function of time X is f(x) = cxe-√x 0 x ≥ 0 otherwise What is the probability that the workers will take more than 10 hours to complete the task?

想問這題怎麼算，感謝🙏
