Find constants a and b in the function f(x)=axe^(bx)such that f(1/7)=1 and the function has a local maximum at x=1/7. a = b =
The rms(root-mean-square) value of a periodic signal s(t) is defined to be rms [s]=(1/T Ss^2t dt)^1/2 where T is defined to be the signal's period: the smallest positive number such that s(t)=s(t+T). What is the rms value of the sinusoid s(t)=Asin(2πf0t)? (Again, writ...
