举一反三
- 设[img=28x19]17da41b38e91a03.jpg[/img]为可导函数,则[img=63x37]17da426f632f014.jpg[/img]的导数是( ) A: f(x) B: f(x)+C C: f '(x) D: f '(x)+C
- X~N(1,1), 密度函数为[img=37x25]18038fe689205b5.png[/img], 分布函数为F(x), 则（ ） A: [img=198x25]18038fe690a03ee.png[/img] B: [img=101x25]18038fe69af96aa.png[/img] C: [img=67x25]18038fe6a3b8e5b.png[/img][img=118x25]18038fe6ab93d6f.png[/img] D: F(x)=F(-x)
- 令F(x):x是有理数,G(x):x是实数。将命题“所有的有理数都是实数,但有的有实数不是有理数”符号化为() 未知类型：{'options': ['17e0a83a4157352.jpgx(F(x)∧G(x))∧[img=8x14]17e0a83a35505d4.jpg[/img]x(G(x)[img=14x9]17e0a73094b5dcf.jpg[/img][img=10x11]17e0a839b915354.jpg[/img]F(x))', ' [img=8x14]17e0a83a4157352.jpg[/img]x(F(x)[img=14x9]17e0a73094b5dcf.jpg[/img]G(x))∧[img=8x14]17e0a83a35505d4.jpg[/img]x(G(x)∧[img=10x11]17e0a839b915354.jpg[/img]F(x))', ' [img=8x14]17e0a83a4157352.jpg[/img]x(F(x)∧G(x))∧[img=8x14]17e0a83a35505d4.jpg[/img]x(G(x)∧[img=10x11]17e0a839b915354.jpg[/img]F(x))', ' [img=8x14]17e0a83a4157352.jpg[/img]x(F(x)[img=14x9]17e0a73094b5dcf.jpg[/img]G(x))∧[img=8x14]17e0a83a35505d4.jpg[/img]x(G(x)[img=14x9]17e0a73094b5dcf.jpg[/img][img=10x11]17e0a839b915354.jpg[/img]F(x))'], 'type': 102}
- 下列函数中为同一个函数的是() 未知类型：{'options': ['f(x)=x,g(x)=[img=25x39]17e43f7e294a229.png[/img]', ' f(x)=x,g(x)=[img=39x24]17e43f7e31cdea3.jpg[/img]', ' f(x)=x,g(x)=[img=35x25]17e43f7e3c419e9.png[/img]', ' f(x)=|x|,g(x)=[img=35x25]17e43f7e3c419e9.png[/img]'], 'type': 102}
- 设 f(x, y) 可微, g(x, y) 也可微, 复合函数 f(x, g(x, y)) 关于 x 的偏导数为 A: [img=99x18]1803497b5fbf17f.gif[/img] B: [img=220x20]1803497b67f53f8.gif[/img] C: [img=278x20]1803497b70d3874.gif[/img] D: [img=156x20]1803497b78c5940.gif[/img]
