On the third input line, you assign the value 10 to the upper left element in arr_2. Finally, you print arr_1 again to verify that none of the values in arr_1 have changed. Technical detail: MATLAB employs a copy-on-write memory management system, where an array may only be copied...

Finding an analytic continuation for ζ(s) is a lot trickier, because there’s no cute way to write it without using an infinite summation (or product), but the basic idea is the same. We’re going to do this in two steps: first turning ζ(s) into an alternating sum that converges...
While there are different types of functionals, calculus of variations is mostly concerned with one in particular: where a definite integral’s integrand contains a (yet to be determined) function. The goal of calculus of variations is to study the changes in these functional while moving from ...
(5.5) The "seed" D¯ -function Φ(U, V ) is the famous scalar one-loop box integral in four dimensions and can be expressed in closed form in terms logarithms and dilogarithms. After the change of variable into U = zz¯ and V = (1 − z)(1 − z¯), the integral can...
This arrangement has O(n) lines and (n) "heavy" nodes to each of w√hich √(n1/3) lines are incident. Moreover, the heavy vertices are lattice points in an n × n integral lattice of the plane (see p. 112 of [4]). We rotate the arrangement clockwise with a suitable small ...
This certainly sounded interesting to me, so I asked James to write a guest post, and here it is. (Many of James' mails had the tag-line "Sent from my iPad".) Over to James. How do you find exact values for the sine of integer angles?
it’s the ratio of circumference to diameter of a circle. And that means that π appears in zillions ofscientific formulas. But it’s not the whole story. (And for example most people have never even heard of theanalog of π for an ellipse—a so-called complete ...
