"Only start and end tangents are enforced, not tangents at all interpolation points. I think your best bet is to make a series of bezier curves (points and tangents) and then join them all together into a single curve afterwards. -- David…"

### interpolated(t) component

So I am trying to solve this problem.  I have a set of points and I want to create a curve that is tangent to all these points in the same direction.  Basically what I want is to curve where I set the inflection points.  I thought the interpolated(t) component was the answer until I looked very close.  While it is much better than the regular interpolated curve, it does seem to be slightly off.  Am I miss reading what this component does?See More

"Figured it out.  Instead of Round(x[,d]) it's Round(x,d). Not sure why the square brackets are listed."

### Round Function

So I am trying to use the round function.  From the expression editor function list is says Round(x[,d])The issue is when I type this in I get an invalid expression (1519) I am sure I don't have something correct with the syntax, but can't figure it out.  Anybody else run into this problem. DennisSee More

"How does that function input syntax work? {x, x^2+3*x+2, 0} Does this syntax allow for the creation of points output directly ? Thanks.   Chris"
