It is solved with the following function: f(x) = A sin(n*π*x/L) Maximum If the function is defined between zero and L, find where it is at a maximum. In terms of probability, what is this telling you physically? Probability For n = 4, write down (but do not solve) the integral you would need to evaluate to see if the object is between 0 and L/3. Please include a sketch.
