Can some one help me out how to configure spine sweep formula? for equation driven spline. right now im having trouble even to type in formula (eyes going crazy and SW text size seams not best to even distinguish how many ((( you have next to each other.

Above is image what im trying to achieve ideally so that i can set height (amplitude) in mm in Equations global vars along with total length form start to end say 200mm  and step/ frequency so i can control starting wave form and ending...

I found this page has formukas that i can use https://endaq.com/pages/sine-sweep-testing

but i can figure out how to port formula to SW :((((

any help would be appreciated :)

tnx
