@snell okay

but like normally they when the r formula isn’t to the power of anything..why is it that the part next to R ( sin(etc) ) speficially must b -1 for min value and 1 for maximum value. Is there a significance behind it? And like why does it change when u add a power. I get the previous explanation but still..

I guess you understood this already..

Oh, its okay, thank you.
