I'm not understanding can anyone please explain clearly.

RMS value means root mean square which by its name only suggests that it is nothing but the square root of mean of squared value of voltage or any quantity to be measured. In this case the function is voltage which can not be represented by a single function.

So the interval of investigation should be broken into respective number sub-intervals where the voltage function can be represented by a single algebraic functions. After getting the square of the functions and do the same as explained in first line.

Why is this 100t not 100 in integration 0 to 1?

Venky said:   1 decade ago
Because from 0 to 1 it is slope function, y=mt use this formula you will y = 100t.

m = 100 i.e, slope. m = (y2-y1)/(x2-x1).

RMS = (1/2) (Integral (x (t)^2))^(1/2).

How come answer 80? I didn't understand.

Rakesh said:   10 years ago
Explain the procedure.

Naresh said:   9 years ago
Why the slope m=100 it is 100v.

How it is, please explain.

Yes in 1 to 2 it should be 100^2.
