Recently I have been doing a lot of double and triple integrals. To my disappointment, Mathematica does not have built-in integral signs for those advanced or special integrals. Fortunately, I have found out a way to introduce those integral signs...
Looks fantastic, this is just what I need for recent work. However, the current algorithm is unable to find some denesting result even when one truly exists, e.g. ones related to non-algebraic numbers and transcendental functions, like this below: ...
Thanks. The `TraditionalForm` trick is useful though imperfect. I agree on you that rearranging expressions in exactly the way I want is truly complicated.
In Mathematica,the inverse hyperbolic functions are displayed with the prefix "Arc" like "ArcSinh[]", which I thought incorrect and misleading. Since the hyperbolic angle is defined by the area of the hyperbolic triangle rather than the arclength of...
