Hello everyone, that's my first discussion (open-ended post), so if there are any improvements to be done, then please don't hesitate in informing about it.
Getting to the point, there's an equation which I've seen in some wiki from Brilliant, and it's really bothering me because I can't understand it at all. I tried to solve it myself, and I got a completely different result. I also entered it in some math computing websites (such as WolframAlpha), but they also gave me completely different results from the equation I've seen around here. I'm going to post both ways (the way I've seen, Computation A, and my way, Computation B) so someone might be able to point which of both are right (or explain why none are right).
I'm still in high-school level on math, but in either way I wasn't able to follow that math. Not completely, but I'll keep an ordered list on how I interpreted the steps in case anyone can clarify anything to me. Each number from the list refers to its respective step in the Computation A equation.
Simplification from previous step, but it makes sense to me.
Now here's my way of solving it when considering that
And by the way, I don't trust my own calculations and methods, so I threw that problem into some online math-computing programs. There are the links:
The results from all of them are 1, but they're machines, so I don't know, they can be possibly doing something wrong (or maybe not).
Please, feel free to correct me, give suggestions, clarify content and explain anything over the context of this problem. Any constructive feedback is welcome!
