想請問這題是怎麼從第二個等號變第三個的？求解微積分大神🥲

3 x -dx=? x+1-vx+l 4 -xv+ : xx+ x(x + 1) dx xlx+1+ 答:原式= (x+1)-(x+1) Set 1 - + x(x +1+Vx+1) dx = f*(x +1+vx + 1 2 16 = x+2Vx+1+c 1 det Jeses dx . √x+1

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？~

只有你 編輯 3. Let f(x) be continuous for 0 SX S1. Suppose further that f(x) assumes rational values only and that f(x) = 1 when x = 1. Prove that f(0) = 4 everywhere. suppose f(x) doesn't have fixed value we have "f(x) EQ jf E= & q> do vsoo for some fro+ f(20) when Ix-xocs, I fix-fixos/>E contradiction with flac is continuous :56o has a fixed value 更多 新增到限時動態 III O
