    How to Prove Log 2 Using Riemann Sums?

    argh... yes. I just checked the errata and it indeed is 2n and not 2^n. Well, given that it is 2n, does anybody have any ideas how to prove it using Riemann sums.

    How to Prove Log 2 Using Riemann Sums?

    No, I (or better the author of the book) mean 2^n. The problem is given just like that. log(x) is just defined the usual way.

    How to Prove Log 2 Using Riemann Sums?

    I changed the equations to latex, hope it is clear now.

    How to Prove Log 2 Using Riemann Sums?

    I have been working on this problem for a while. I am supposed to prove that log 2 = \lim_{n \rightarrow \infty} \frac{1}{n+1} + \frac{1}{n+2} + ... + \frac{1}{2^n}. The problem is that I have a hard time figuring out how I am supposed to prove that something is equal to a transcendental...

    Solving Evil Torque Problem: Get Help Here!

    ahh... so the overall point of application of the gravity force is in the middle of the rod and therefore r is only 1m instead of 2m?

    Well, I don't know why it is twice more. That is the problem. It seems that r should be 2m for sure. I suppose it could be F since the gravity is only acting on half the mass?

    Solving Evil Torque Problem: Get Help Here!

    Hi I have a problem for which the given solution makes no sense to me. A 200 kg plank of length 2m is attached by a hinge at one of its ends to a wall. It is held in place horizontally by a string. The string breaks and I am supposed to find the torque at that point. (See attached image)...

    Just starting to looking into things

    Theoretical Physics with little or no math is an oxymoron. Theoretical physics really is only math and how the mathematical results could apply to the world.

    Which Degree Best Prepares for a Career in Quantum Computing?

    That depends... I would say if you want to work on theoretical aspects of quantum computing (algorithms and general theory) it would be mathematics. If you are interested in the technical aspects then it would be physics or electrical engineering although I would lean towards physics.

    Schools A question about Canadian Universities

    In this case you should look for a new educational consultant... I am sure top tier Canadian institutions are on par with ours. And with knowing how to plug in numbers into an equation you are not going to get far anywhere in the world...

    Schools A question about Canadian Universities

    I know two people who went to a CC. One of them went to CMU for CS and the other to Harvard. Most of their courses were accepted since they were lower level courses.

    Yes, you miss out on a lot of material on series. But you can leave that for college...
