AI Thread Summary
For inquiries about forecasting, it's recommended to post in relevant sections based on the specific focus of the question. Time-series analysis questions should be directed to probability and statistics, while deterministic dynamical systems belong in differential equations. If the question pertains to a specific field like economics, the corresponding section is more appropriate. Users can expect their questions to be moved to the correct section if initially posted incorrectly. Engaging in the right forum section enhances the likelihood of receiving accurate answers.

kindly advise where can I ask a question about forecasting?
can it be here? or elsewhere? .. thank you...

It is a very broad topic.
For time-series analysis I would choose one of the sections on probability and statistics.
For deterministic dynamical systems I would go to differential equations.
If the question strongly depends on specifics of a particular field (such as economics), I would perhaps go to the corresponding section instead.

In any case, if you choose a section that you think is correct, but it turns that your question is better placed in another section, it will probably be moved there without much difficulty.

Thread 'Video on imaginary numbers and some queries'

Hi, I was watching the following video. I found some points confusing. Could you please help me to understand the gaps? Thanks, in advance! Question 1: Around 4:22, the video says the following. So for those mathematicians, negative numbers didn't exist. You could subtract, that is find the difference between two positive quantities, but you couldn't have a negative answer or negative coefficients. Mathematicians were so averse to negative numbers that there was no single quadratic...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

Thread 'Unit Circle Double Angle Derivations'

Thread 'Unit Circle Double Angle Derivations'

Here I made a terrible mistake of assuming this to be an equilateral triangle and set 2sinx=1 => x=pi/6. Although this did derive the double angle formulas it also led into a terrible mess trying to find all the combinations of sides. I must have been tired and just assumed 6x=180 and 2sinx=1. By that time, I was so mindset that I nearly scolded a person for even saying 90-x. I wonder if this is a case of biased observation that seeks to dis credit me like Jesus of Nazareth since in reality...
