wave number is equal to 2π times frequency divided by velocity. For the angular formula, however, you can take one more step. It turns out that 2πfis equal to the angular frequency, as symbolized by the Greek letter omega (ω), which you can use to simplify the formula even further...
Be mindful of causing too many recompositions in the onSizeChanged lambda. Excessive use can lead to performance issues, especially if the UI is complex. It’s generally a good practice to keep the logic inside the onSizeChanged callback minimal and efficient. Potenti...
There is a special number between 0 and 1 called the LAMBDA parameter which adjusts how much future reinforcement signals should be weighted. When LAMBDA is equal to zero, then the sum total of all expected future reinforcement is simply estimated by the current immediately received reinforcement....
