I would be greatful for any help with the following problem. I know i need to find the dirivative of v and then from this i can transpose to find the unknown value of x. Just don't seem to be able!
Q. The velocity, v, of a signal in a cable at a distance x is given by :
v = K x ln (1/x) where 0<x<1 ( x is the algibraic x )
where K is a positive constant. Find the value of x which gives the maximum velocity.
Thanks again, James.
