Hololens 2 Multi-User Capabilities error DllNotFoundException: AzureSpatialAnchors

Question

I've been following this tutorial https://docs.microsoft.com/en-us/windows/mixed-reality/develop/unity/tutorials/mr-learning-sharing-02 to make a Hololens 2 app that can be used by 2 or more users, however, I haven't been able to make it work, because after finishing the tutorial and trying to run the app, I get this build error message:

DllNotFoundException: AzureSpatialAnchors

I'm not sure what i'm doing wrong, I tried googling this problem but I seem to get nowhere. pls keep in mind that i'm a new developer unu I included an image to give a better idea of the problem, it seems to be the only error message D:

(I tought the problem may have been something to do with my spatial anchor resource on azure, but even after creating a new resource and pasting the new ids, it seems to still have the problem unu. also, i do have a hololens 2 visor, so i'm sure the problem doesn't have to do with the emulator while pressing play.)

i hope the image helps

Answer 1

I am not sure if this answers your question as it is not very detailed, but here is a link

https://docs.sympy.org/latest/modules/simplify/simplify.html\

E.g.

>>> from sympy import simplify, cos, sin
>>> from sympy.abc import x, y
>>> a = (x + x**2)/(x*sin(y)**2 + x*cos(y)**2)
>>> a
(x**2 + x)/(x*sin(y)**2 + x*cos(y)**2)
>>> simplify(a)
x + 1

Answer 2

As @oscar-enjamin pointed out, sqrtdenest is a good first stop. I would also add that if you have a number that you think can be written in terms of other numbers, nsimplify might be able to help:

>>> from sympy import nsimplify, sqrt, divisors
>>> eq=sqrt(3 + 2*sqrt(2))
>>> nsimplify(eq,[sqrt(2)])
1 + sqrt(2)

>>> eq = sqrt(19 + 3*sqrt(2) + 6*sqrt(3) - sqrt(10))
>>> nsimplify(eq, [sqrt(i) for i in divisors(int(eq**2)) if i - 1])
-sqrt(2) - sqrt(6)/2 + sqrt(3)/2 + sqrt(5)/2 + 3/2 + sqrt(15)/2 + sqrt(30)/2
