calculate the RMS (root mean square) of this function.
the period T=4
the formula is
i get a latex error here the code is:
the solution says that they divide the graph into 4 triangles
and they sum their areas
but they dont use the integral?
why they say (4t)^2
from where the 4t comes from?
why they say that its the root of the area
why they dont divide by the period?
