若n阶方阵满足[img=117x24]1802f3265f152f9.png[/img],则[img=31x22]1802f3266913708.png[/img]=
举一反三
- 若f(x)+f(-x)=0, 则[img=95x39]17da608af452d96.jpg[/img]. 若f(x)=f(-x), 则 [img=170x38]17da60541207426.jpg[/img]
- 已知f(x)具有任意阶导数,且[img=18x32]17d622a39cdd9ca.png[/img](x)=[img=75x35]17d622a3a717d8a.png[/img]则当n为大于2的正整数时,f(x)的n阶导数[img=34x34]17d622a3b2d544c.png[/img](x)=[img=129x35]17d622a3c15d078.png[/img] ( )
- 若f(x)与f(x)都是n次多项式,且在n+1个互异点[img=15x17]18030752905fe56.png[/img]上[img=89x25]18030752981507a.png[/img],则f(x)=g(x)
- 设随机变量X的概率密度为f(x),则f(x)一定满足( ). A: 0≤f(x)≤1 B: [img=183x53]1803b451bb3373a.png[/img] C: [img=133x51]1803b451c807078.png[/img] D: f(+∞)=1
- 设f(x)=[img=15x18]17da42685cb8d76.jpg[/img],则f【f'(x)】=
