[微積] 大一微積

[kelvin811 (sheila)]

 因為大學微積分全還給老師了>"<所以想問問~
Q1. Give an example of a function that is not integrable on the interval
    │2,4│(you don't need to show that it's not integrable)

Q2. Solve the initial value problem dy/dx=4x(x平方+8)-1/3次方,y(0)=0

Q3. Find the average value of f(x)= -5(x平方)-1 on the interval │0,2│

Q3. Find the area between the curve y=(x-2)(x-4)(x-6) on │-1,7│ and the
    x-axis

麻煩還記得的鄉民、很厲害的鄉民幫我解一下
謝謝~

→ tenraku2109 :Q1 : 高斯函數 ,有斷點3 , 不連續不可積分
→ tenraku2109 :Q3:1/2∫-5x^2-1 dx定積分0~2
→ suhorng     :[x] 是黎曼可積
→ jollic      :看到不能積分，第一直覺就是想到 Dirichlet Function
