• In this section we want to look at an application of derivatives for vector functions. Actually, there are a couple of applications, but they all come back to needing the first one.

With vector functions we get exactly the same result, with one exception. While, the components of the unit tangent vector can be somewhat messy on occasion there are times when we will need to use the unit tangent vector instead of the tangent vector. First, we could have used the unit tangent vector had we wanted to for the parallel vector.

However, that would have made for a more complicated equation for the tangent line. Do not get excited about that. Next, we need to talk about the unit normal and the binormal vectors. The unit normal is orthogonal or normal, or perpendicular to the unit tangent vector and hence to the curve as well. They will show up with some regularity in several Calculus III topics.

The definition of the unit normal vector always seems a little mysterious when you first see it. It follows directly from the following fact. To prove this fact is pretty simple. From the fact statement and the relationship between the magnitude of a vector and the dot product we have the following. Also, recalling the fact from the previous section about differentiating a dot product we see that. The definition of the unit normal then falls directly from this. 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.

If your device is not in landscape mode many of the equations will run off the side of your device should be able to scroll to see them and some of the menu items will be cut off due to the narrow screen width. Here is the tangent vector to the curve. Show Solution We first need the unit tangent vector so first get the tangent vector and its magnitude.In statistics, there are many tools to analyze the data in detail and one of the most commonly used formula or method is the Normalization method.

Normalization and standardization have been used interchangeably but they have usually different interpretations and different meanings altogether. Normalization in layman terms means normalizing of the data. Normalization refers to a scaling of the data in numeric variables in the range of 0 to 1.

Step 1 : From the data the user needs to find the Maximum and the minimum value in order to determine the outliners of the data set. Step 3: Value — Min needs to be determined against each and every data point in the set. Step 4 : After determining all the values in the data set the value needs to be put in the formula i.

This has been a guide to Normalization Formula. Here we discuss how to calculate Normalization along with practical examples. We also provide a Normalization calculator with downloadable excel template. You may also look at the following articles to learn more —.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. My question is, why do we do this thing, I mean what do we get out of this equation? The Cartesian coordinate system that we use is an orthonormal basis consists of vectors of length 1 that are orthogonal to each other, basis means that any vector can be represented by a unique combination of these vectorswhen you want to rotate your basis which occurs in video game mechanics when you look around you use matrices whose rows and columns are orthonormal vectors.

As soon as you start playing around with matrices in linear algebra enough you will want orthonormal vectors. There are too many examples to just name them. At the end of the day we don't need normalized vectors in the same way as we don't need hamburgers, we could live without them, but who is going to?

Any vector, when normalized, only changes its magnitude, not its direction. Also, every vector pointing in the same direction, gets normalized to the same vector since magnitude and direction uniquely define a vector.

Hence, unit vectors are extremely useful for providing directions. Note however, that all the above discussion was for 3 dimensional Cartesian coordinates x, y, z. But what do we really mean by Cartesian coordinates? Turns out, to define a vector in 3D space, we need some reference directions. These reference directions are canonically called ijk or i, j, k with little caps on them - referred to as "i cap", "j cap" and "k cap". Note: I will no longer call them by caps, I'll just call them i, j, k.

They are the basis of all Cartesian coordinate geometry. There are other forms of coordinates such as Cylindrical and Spherical coordinatesand while their coordinates are not as direct to understand as x, y, zthey too are composed of a set of 3 mutually orthogonal unit vectors which form the basis into which 3 coordinates are multiplied to produce a vector.

So, the above discussion clearly says that we need unit vectors to define other vectors, but why should you care? Because sometimes, only the magnitude matters. You would not want to thrown in a pesky direction, would you? I mean, does it really make sense to say that I want 4 kilograms of watermelons facing West? Unless you are some crazy fanatic, of course.

Other times, only the direction matters. You just don't care for the magnitude, or the magnitude just is too large to fathom something like infinity, only that no one really knows what infinity really is - All Hail The Great Infinite, for He has Infinite Infinities Sorry, got a bit carried away there. In such cases, we use normalization of vectors. For example, it doesn't mean anything to say that we have a line facing 4 km North. It makes more sense to say we have a line facing North. So what do you do then?

You get rid of the 4 km. You destroy the magnitude. All you have remaining is the North and Winter is Coming.

Do this often enough, and you will have to give a name and notation to what you are doing. You can't just call it "ignoring the magnitude".

That is too crass.

You're a mathematician, and so you call it "normalization", and you give it the notation of the "cap" probably because you wanted to go to a party instead of being stuck with vectors.Summary : The vector calculator allows the calculation of the norm of a vector online.
