A learning differs from supervised learning in not needing labelled input/output pairs be presented, and in not needing sub-optimal actions to be explicitly corrected. Instead the focus is on finding a balance between exploration (of uncharted territory) and exploitation (of current knowledge) .Semi...

If we’re given the ladder angle, the minumum friction coefficient to prevent slipping is μ=1+tan 2θ−tanθ This one of the two solutions to a quadratic equation. The other gives a negative friction coefficient, which we don’t care about. As the ladder angle approaches 0°, the ...
