@tony: The reason why a+b=7 can be seen by evaluating both sides of the second equation mod 11.

@symbolipoint: I think mathman may have been responding to the original post when he was commenting. @Nugatory: log 1 = 0 and log 2 ≈ 0.6931... -Junaid :-p

Any advice about the pros/cons of using Giancoli's Physics for Scientists and Engineers vs. University Physics for self-studying Calculus based physics. I am currently reading through Giancoli's non-calculus based physics book and am enjoying it and finding it very clear and well-written. I was...

I'm not quite sure what you are doing. Also, if your goal is to solve for k, I'm not sure why you have x in your equations. -Your first equation is quadratic in x -Your second equation is linear in x -Your third equation is again quadratic in x -The remainder of your equations don't have x -Junaid

If the inequality has only one variable (as yours does), you would graph the solution on a number line. If the inequality has two variables (x and y), then you could graph the solution on a Cartesian plane.

I think chiro's words of wisdom are priceless. You have to take time out and think about what success and happiness mean to you. Sometimes these have been defined so consistently and repeatedly from our youth that we can't imagine that any other definitions or avenues to them might exist and...

Thanks. I will read up on that.

I know that the Law of Conservation of Mechanical Energy can be derived using Newton's Laws and Kinematics. I believe that at very small scales, where Newton's Laws no longer apply, that Conservation of Mechanical Energy is still true (or is it Conservation of Energy in general, not sure). 1)...

Is the problem: \int\sqrt{\frac{x}{2}-x}\space dx or \int\sqrt \frac{x}{2-x}\space dx ?

You're welcome.

88P = 10000a + 2930 + b - Hint 1: Think of the numbers that divide the LHS. They must divide the RHS as well. - Hint 2: Show that a + b = 7 - Hint 3: Show that b is even This will narrow the search to only four possibilities. Junaid Mansuri

Congratulations on quitting smoking. That's an amazing and wonderful thing you did.

The distance between a point and a line is found by finding the shortest distance between the given point and the line. This shortest distance is found by drawing a perpendicular segment from the point to the line. Look at the picture you have. The center of the square is at the origin (0,0). -...

Yes, that's an important point. You have to keep in mind that this problem is about finding the sum of a finite series, not an infinite series. -Junaid
