i tried to get the linear interpolations using the 'user defined' option. what actually should be simple enough to do using the 'table' option, is very hard with 'user defined' function using expressions. however, i did try and got this thing to work. we need to do some manual calculations before entering the data. for example, i made a rotary joint, which needs to rotate one full circle at varying speeds. Say 0 to 90 degree in 5secs, 90-270 deg in 5 secs and 270-360 deg in 20 secs. for this i should key in the following expressions and domains
i am arriving at the expressions based on equation of line (y=mx+c). there should be a more simple approach. if any of one knows, please enlighten us all.
