Homework Statement
Find the average of a sinusoidal function over 1.5 cycles
2880*sin(wt - 30 degrees)
Homework Equations
The Attempt at a Solution
Alright so
1/( (3*pi)/2 - 0) * integral[0, (3*pi)/2] 2880*sin(wt - 30 degrees) dt
I shift it over to the origin because it shouldn't effect the average no matter the phase?
(5760/(3pi)) * integral[0, (3*pi)/2] 2880*sin(wt) dt
- (5760/(3pi))*cos(t)|[0, (3*pi)/2]
- (5760/(3pi))*(0-1)
1920/pi
Does this look ok?
