## Homework Statement

[tex]

i_1=10+20sin(377t+(\pi /6))[/tex]

[tex]i_2=-30[/tex]

[tex]i_3=10+10sin(100t-(\pi/4))[/tex]

[tex]i_4=10sin(377t)[/tex]

[tex]i_T=\sum _i i_i

[/tex]

What I am wondering is how you go about calculating the average value for the linear combination of all three functions. Also, how would one calculate the rms for such, given the periods are all different?
