## What is the connection between vector functions and space curves?

There is a close connection between space curves and vector functions. Specifically, we can determine a vector function which traces along a space curve C (provided we put the tail of the vectors at the origin, so they are position vectors). Likewise, any vector function defines a space curve.

## How do you represent a curve in space in vector form?

The graph of a vector-valued function of the form ⇀r(t)=f(t)ˆi+g(t)ˆj+h(t)ˆk is called a space curve. It is possible to represent an arbitrary plane curve by a vector-valued function. To calculate the limit of a vector-valued function, calculate the limits of the component functions separately.

**How do you find the Arclength of a vector?**

If a vector-valued function represents the position of a particle in space as a function of time, then the arc-length function measures how far that particle travels as a function of time. The formula for the arc-length function follows directly from the formula for arc length: s=∫ta√(f′(u))2+(g′(u))2+(h′(u))2du.

**How do you measure curvature of a curve?**

To measure the curvature at a point you have to find the circle of best fit at that point. This is called the osculating (kissing) circle. The curvature of the curve at that point is defined to be the reciprocal of the radius of the osculating circle.

### What is a Binormal vector?

The binormal vector is defined to be, →B(t)=→T(t)×→N(t) Because the binormal vector is defined to be the cross product of the unit tangent and unit normal vector we then know that the binormal vector is orthogonal to both the tangent vector and the normal vector.

### What is the purpose of space filling curve?

A space-filling curve (SFC) is a way of mapping the multi-dimensional space into the one-dimensional space. It acts like a thread that passes through every cell element (or pixel) in the multi-dimensional space so that every cell is visited exactly once.
