 Nov 5 comment Combinatorics: When To Use Different Counting Techniques Ok, that is really simple. Thank you, Austin! Nov 5 comment Combinatorics: When To Use Different Counting Techniques @amWhy I agree. Nov 5 comment Combinatorics: When To Use Different Counting Techniques This is FABulous! Could you please also answer the second to last one, where a constant is used? Nov 5 comment Combinatorics: When To Use Different Counting Techniques @amWhy Yes, that is correct. Basic problems are just that, basic, and not to hard to grasp.

If you found my answer helpful, could you accept the answer, please? Oct 11 accepted How is $2 + e^{t^2} - e^{-t^2}$ Equal to $(e^t + e^{-t})^2$? Oct 11 comment How is $2 + e^{t^2} - e^{-t^2}$ Equal to $(e^t + e^{-t})^2$? Oh... Thank you for making that clear. The \frac{e^t}{e^t} cancel to give one. That is clear in the way you broke it up. Unfortunately, I was given the longer expression to start with, and had to see if it simplified, so I didn't have the opportunity to work backwards.

Just what I was looking for! Thank you, Arturo! Mar 15 accepted Divide with remainder $\frac{x^2}{x^2 + x + 2}$ Mar 14 accepted Why Doesn't This Integral $\int \frac{\sqrt{x^2 - 9}}{x^2} \ dx$ Work? Mar 14 accepted Equivalent to \begin{align}\int \cos{\left(2x\right)} \ dx\end{align}?
