Help needed to plot points along a curve

Im still a nooblet when it comes to grasshopper so have mercy please:-)

I want to plot points along a curve, in series, where x increases by 400 for subsequent points and y occurs wherever the x value meets the curve.

the mathematical equation as far as i know is : y= 400n/tan

can someone please explain how to set this up?

it would be greatly appreciated

You'll need to create the equally spaced lines,then use Curve|Line intersection to find the points. How you set up the lines is up to you (incidentally, you could also use planes instead of lines). You can either divide an axis, or use Series or Range components or a dozen other ways. If you want tight control over the spacing and amount of lines, I recommend using Series, then use the resulting numbers to create XYZ points (where the Series output becomes the X input). Once you have those points you can create lines using the Line SDL component.

Well this is what i have at the moment..a bottom and top rail with those objects at points between them..i need to make sure the points are spaced a specific value along x..
