[a,b]上的可积函数f(x)与g(x)满足[img=90x25]18038394a57dde0.png[/img],则[img=170x52]18038394afe8d2d.png[/img]
举一反三
- [a,b]上的可积函数f(x)不恒等于g(x),则[img=190x52]1802dc823ce4e0e.png[/img]
- 若函数f(x)在区间[a,b]上可积,函数g(x)在区间[a,c]上可积,且[img=93x21]17e0a6f1e01da1c.png[/img],则[img=167x39]17e0a6f1e88c67f.png[/img]
- 设函数f(x)在[a,b]上可积,且[img=104x39]17e0a6f0cc61b64.png[/img],则f(x)在[a,b]上恒等于零
- 函数f(x)在[a,b]上可积,则对任意的[img=65x25]1802dc825999131.png[/img],f(x)在[a,c]上可积
- 函数f(x)在[a,b]上可积,则对任意的[img=65x25]18038394b8a5739.png[/img],f(x)在[a,c]上可积
