I'm a 2nd year physics major thinking about switching to applied math with a concentration in quantum mechanics. I was wondering if anyone knew any possible career paths that could arise from this degree, and also if a career in a more econ/finance/business related field would be a viable...

Yes, but I don't understand how it could be sloping away from the ladder using the given values for the angles. If the wall makes an angle of 2theta with the ground, and the angles the ladder makes with the wall and the ground are equal, wouldn't 2theta=90 degrees?

But what if the wall is not vertical, but sloping away from the ladder at an angle to the ground of 2theta? Arrange the ladder so it makes the same angle with the wall as it makes to the ground Wouldn't 2theta just equal 90 degrees then? Because 2theta+theta+theta=180 degrees in which...

A uniform ladder leans safely against a vertical wall at an angle 45° to the horizontal ground. The wall is 100% slippery, while at the ground the coefficient of friction is µ . Prove that since the ladder is not falling, µ \geq 0.5 I've attempted to solve this, and think I have...
