### How to make a Line[] with no end?

I'm trying to do this: In this graph, the secant points are aproximated in order to become the tangent, it seems I need some kind of function which plots a line based on two points and it's points ...

### How to restrict the motion of a Manipulate-generated Locator along a line?

If one uses a stand-alone locator and needs it to only be movable along a curve, say, defined by a function f[x], one can use a simple construct: ...

### Manipulating several values from the same interval

Some of my calculations depend on the choice of several values from the interval [-2, 2] (it is more or less interpolation of a fixed function using the points as parameters). I want to create a ...

### Help me plot a tangent with a Sin curve [duplicate]

Hi just wondering how to graph the tangent as well as this curve on the same graph : f(x)= Sin[x] at x=0 where the gradient of the tangent is 1
The function $4-x^{2}-2y^{2}$ Set $y = 1$ Then <1,1,1> And its derivative at $y = 1$ is $$f'(x,1) = -2x$$ The following plot the curve at $y = 1$ intersecting the surface, and the derivative ...
