 Jul23 comment What are some conceptualizations that work in mathematics but are not strictly true? @Semiclassical Can you clarify the mathematical objections that would raise? I'm curious to know. Mar19 comment Non-invertible operators Certainly - both questions could be answered in a purely mathematical context.

Apr1 comment Best Fake Proofs? (A M.SE April Fools Day collection) I'm going there this summer myself. I'm part of the "new generation," I see.

Editing... Mar1 comment Calculate the angle between two vectors What you did used the dot product, which is usually the standard way to find angles. However, because of your requirement for angles to be oriented, the dot product will not work. I'll elaborate a bit more in my answer where I can more freely LaTeX. Mar1 answered Calculate the angle between two vectors Feb21 accepted Why $\int_{-1}^1 \frac{1}{x^3}\, \mathrm{d} x \neq 0$? Feb21 comment Why $\int_{-1}^1 \frac{1}{x^3}\, \mathrm{d} x \neq 0$? So am I right in saying that the Cauchy Principal Value does not equal the value of the integral because in calculating the Cauchy Principal Value, one of the two integrals must still contain the x-value of 0? Furthermore, how would someone go about calculating the true value of the integral rather than simply its Cauchy Principal Value? While I realize the conceptual difference between one limit and two limits, I fail to see how the solution will differ between these two cases.

Find the values of $x$ When you did it graphically, you may not have set your calculator window to be large enough.
