plane areas

Find the area bounded by the curve y = ln x/x, the x-axis and the maximum ordinate.

ans. 1/2

The boundaries you described do not bound a closed region. Maybe you can rephrase your question to make it more clear.

However, the area bounded by y = ln x / x, the x-axis and the vertical line through the maximum ordinate is equal to 1/2.
