If you plot y as a result of sin(x), with the position on the x axis changning linearly with the input to the sine function and the factor you scale the result with (amplitude) being constant, you get your ordinary sine curve. Change any of…"
Thanks for contributing your thoughts on GH pain points. I'd like to invite you to an alpha test list for Flux's upcoming product, which is hoping to address some of the issues you are having. Would be great to get…"
