Finding the rms

  • #1
1. find the rms value of i=1/3sin3t between t=0 and t=1/10



2. not sure of the method or the formula i may need



3. Any help appreciated

For continuous functions the RMS over a time interval is

[tex] \sqrt{ \frac{1}{T_2 - T_1} \int_{T_1}^{T_2} [f(t)]^2 dt [/tex]

rms is root mean squared

[tex]

V_{rms} = \sqrt{\frac{1} {(t_1-t_0)}\int_{t_0}^{t_1} v(t)^2 dt}
[/tex]
