did you also get the same answer as mine?

It should say:If you remember some posts back, sqrt(2) / 3 is the answer that I got.
If you remember some posts back, I*sqrt(3)/2 is the answer that I got.
How did you get this Hayato? Every time I've done it I get my answer (obviously).I got i*sqrt(2/3).
I wonder what was not right about the way I did it.
The area of the first little triangles is:
One Triangle = 0.5*base*height = 0.5*(T/4)*i^2
But there are two of them, so the total area of the first half is double that:
Both Triangles = 2*0.5*(T/4)*i^2 = (T/4)*i^2
Area of the second half (the square) is simply:
Square = base * height = (T/2)*i^2
Add up all the area and you get:
Total Area = (T/4)*i^2 + (T/2)*i^2 = (3/4)Ti^2
Divide by the total of the period to find the average area over time and you get:
Average Area = (1/T)(3/4)Ti^2 = (3/4)i^2
FInally square root the whole thing to get:
RMS = i*sqrt(3)/2
