1. ### Proof of the Lindemann-Weierstrass Theorem

I am wanting to find a good proof of the Lindemann-Weierstrass Theorem. Most importantly I need the part that states that eα is transcendental where α ≠ 0 is algebraic. What are good online resources or books for the proof? Thank-you.
2. ### Determining a formula for a (sub)sequence

I currently have the first 125,256 terms of a sequence of natural numbers. I need to find a formula for any non-finite sub-sequence. Are there any good methods for obtaining such a formula? I can already say that it isn't a linear distribution, and I highly doubt it being polynomial (although...
3. ### Principal root of a complex number

Homework Statement I am doing a problem of a contour integral where the f(z) is z1/2. I can do most of it, but it asks specifically for the principal root. I have been having troubles finding definitively what the principal root is. Anyplace it appears online it is vague, my book doesn't...
4. ### Verify that the Stokes' theorem is true for the given vector field

This is a problem from an old final exam in my Calc 3 class. My book is very bad at having examples for these types of problems, and my instructor only went over one or two. Help would be much appreciated. Homework Statement Verify that the Stokes' theorem is true for the vector field...
5. ### Need help understanding Lagrange multipliers at a more fundamental level.

I understand that for Lagrange multipliers, ∇f = λ∇g And that you can use this to solve for extreme values. I have a set of questions because I don't understand these on a basic level. 1. How do you determine whether it is a max, min, or saddle point, especially when you only get one...
6. ### Use Lagrange multipliers to find the max & min

Homework Statement Use Lagrange multipliers to find the maximum and minimum values of the function subject to the given constraint. f(x,y) = exy; g(x,y) = x3 + y3 = 16 Homework Equations ∇f(x,y) = λ∇g(x,y) fx = λgx fy = λgy The Attempt at a Solution ∇f(x,y) = < yexy, xexy > ∇g(x,y) = <...
7. ### Programs What can one specialize in for a MS/PhD in Mathematics?

What is a list of areas of focus for Masters/PhD pursuers for Mathematics? What has the best future prospect for careers?
8. ### Genetic Modification of a Live Organism Is it Possible?

*** I know this is of questionable ethics, but I am asking a hypothetical *** If we had a human of adult age, let's say, age 20-30. Would it be possible to genetically modify all cells in the body and make the changes take effect in a realistic manner? If so what would be the limits and steps...
9. ### Converting an Integral to a Rieman Sum

I know I should know this, but how would one convert a typical integral into a Rieman Sum? ∫0n sinx + x dx for whatever n. for example.
10. ### Find symmetric equations for the line of intersection of the planes

Homework Statement Find symmetric equations for the line of intersection of the planes The planes: 5x - 2y - 2z = 1 4x + y + z = 6 Homework Equations r = r0 + tv x = x0 + at y = y0 + bt z = z0 + ct The Attempt at a Solution I have attempted this in many different manners and would like...

19. ### Converting between bases without base 10 mid-step

I am currently trying to go between any two bases which are between and including base 2 to base 10. (i.e, base 10 to base 3, base 4 to base 6, etc...). Is there an equation or set of formulas for a one-step transition between the bases (or one-way method, rather than converting to base-10 then...
20. ### The Basics

I am a high school senior who is new to these forums. So far, I have found them intriguing, but I do have a question that I have asked many of my teachers, but sadly, had no real response. What are the basics of quantum physics? Basic concepts, theories, equations for example. I haven't been...
