I have the following expansions:
$\frac{a+b-\sqrt{a^2-b^2}}{\sqrt{a+b}}$ and $a>b>0$
Obviously we can simplify it further by hand $\sqrt{a+b}-\sqrt{a-b}$, but Mathematica doesn't know how to ...

I found a very strange result in Integrate command. I numerically integrated
$$\int_{-1}^1 \int_{-1}^1 \frac{1}{|x|^{2/5} |y|^{3/10} |x-y|^{7/10}} dx dy.$$

For my Calc III class, I need to find $T(t), N(t)$, and $B(t)$ for $t=1, 2$, and $-1$, given $r(t)=\{t,t^2,t^3\}$.
I've got Mathematica, but I've never used it before and I'm not sure how to coerce ...

I have two lists of values
xx = {0.1, 0.3, 0.35, 0.57, 0.88, 1.0}
yy = {1.2, 3.5, 4.5, 7.8, 9.0, 12.2}
I want to make a scatter plot (list plot) with xx as x ...

Consider the recurrence relationship
d[0] = 0;
d[i_] := (1 + Sqrt[1 + 4 d[i - 1]^2])/2 /; i >= 1
which generates the following sequence (generated by using <...
