 Nov 8 comment Finding upper bound for sum @MarcusStuhr Hang on a second, doesn't that give $\ln \sqrt {61}$ rather than $\ln 61$?

This site is for people of any mathematical ability who may not spot things as easily as you do. Aug 19 comment Cube root of complex number without trigonometric functions Please learn Mathjax before posting so we can read the formulas that you write Aug 9 awarded Quorum Aug 9 accepted Fraction of original velocity in series of elastic collisions Aug 9 asked Fraction of original velocity in series of elastic collisions Jul 5 comment How to calculate $\int \frac{\sin x}{\tan x+\cos x} \, dx$ I'd probably try splitting it into partial fractions Jun 28 answered Question about logarithmic eqations Jun 28 revised Question about logarithmic eqations fixed formatting Jun 28 comment Question about logarithmic eqations It doesn't have a solution in terms of elementary functions, you need to use the Lambert W function Jun 28 suggested approved edit on Question about logarithmic eqations Jun 23 comment Why does $\cos(x) + \cos(y) - \cos(x + y) = 0$ look like an ellipse? Completely unrelated, but that is one of the coolest graphs I've ever seen Jun 23 accepted Roots of a sixth degree polynomial Jun 23 asked Roots of a sixth degree polynomial Jun 22 accepted Integrating $\frac{1}{1+e^x}$ Jun 22 comment Integrating $\frac{1}{1+e^x}$ Thanks for the answer, I can see the solution now. However I would appreciate it if you could explain why my working doesn't work. I can't see the mathematical issue with it Jun 22 asked Integrating $\frac{1}{1+e^x}$
