SE users I was given the problem: Find the volume of a frustum of a right circular cone with height h, lower base radius R, and top radius r. My working l...

I would like to find the integral of $\int_0^\infty\exp(-u-\exp(-ku))\,du$ for $k>0$. This is related to the gumbel distribution(http://en.wikipedia.or...

I'm having a problem understanding scientific notation. What is the difference between the following: $$\text{5e2, 5e-2, -5e2, -5e-2}$$

Say we are given the unit circle, defined by all real numbers $x,y$ such that $x^2+y^2=1$. Now, if one tried to solve explicitly for $y$, one would get th...

I am confused by the notation comma. I know that the comma means 'AND' in Set theory as gate ($a \land b=a$ AND $b$), But we write solution of e...

How can I calculate something like $(i+1)^{33}$ or similar high exponent without the use of a calculator?

What is the derivative of $\sin a x$ where $a$ is a constant. Actually, I'm studying Physics and not so well-versed with calculus. So, I have studied...

We know that for a cylinder $$ V = \pi r^2 h $$ This formula is easily visualized as a stack of $h$ circles with radius $r$. However, as a little experime...

So the question is listed below as a picture, I realize I have to subtract the min and max after inputting them into the equation. So far I think it would...
