Undergrad Can You Solve These Challenging Math Club Problems?
n=1 : 1(n+1) = 2 n=2 2(2+1) = 6 n=3 3(4) = 12 n=4 4(5) = 20 ... So n simply represents the set of number going 1 to 100. Then we can reduce the series by using the same rule as a telescopic series to get the sum. http://en.wikipedia.org/wiki/Telescoping_series- Vardd

Undergrad Can You Solve These Challenging Math Club Problems?
Question 2 : 1000 - (2x) = 3x Solve for x x = 200 Test it : 1000 - (2*200) = 600 3*200 = 600 So they say 600 at the same time.- Vardd

Undergrad How to prove ln(x) < sqrt(x) for all x>0
Hi Grossgermany, To answer the question, I'm assuming you have a rough idea of Calculus. We know that the derivative of a formula, tells us the rate of change of the formula. We also that both formulas are always positive. (Sorry no Latex I tried to make it works, but i failed. )... -

Graduate Why do some integrals at infinity give finite values while others don't?
I've asked myself this questions a few years ago, and It is not be the official answers but it helped me understand the "Why". Integral(0 to infinity) ( 1/x) dx = Ln(x) +C , where C = 0. So we can clearly see that as the n increase, it doesn't converge to any number. An other way of... -

Undergrad Is the Big Bang Still Happening and How Does it Influence the Universe?
Of what I understand, the Big Bang was an instantaneous. The big bang represent the Singularity, where a Model must be use. Then, researchers has been able to go back up to 10^-37 seconds after the singularity happened. Then, still based on the Model, out of the big bang, the universe cooled...- Vardd
