Vedclass · Answer

(b) 1. rms value =$\frac{{{x_0}}}{{\sqrt 2 }}$

     2. ${x_0}\sin \omega t\cos \omega t = \frac{{{x_0}}}{2}\sin 2\omega t \Rightarrow rms\;value = \frac{{{x_0}}}{{2\sqrt 2 }}$

     3. ${x_0}\sin \omega t + {x_0}\cos \omega t \Rightarrow rms\;value = \sqrt {{{\left( {\frac{{{x_0}}}{{\sqrt 2 }}} \right)}^2} + {{\left( {\frac{{{x_0}}}{{\sqrt 2 }}} \right)}^2}} $

      $ = \sqrt {x_0^2} = {x_0}$
