BEFORE WE BEGIN This post is about how to use vector math and trigonometric functions in Maya, it is not a linear algebra or vector math course, ...

This post will give you an introduction to the most important concepts of Linear Algebra that are used in Machine Learning.

Math is like an octopus: it has tentacles that can reach out and touch just about every subject. And while some subjects only get a light brush, ...

You just add or subtract each value of the first Matrix with its corresponding value in the second Matrix. See below:

We already know the point at the center of the sphere (3, 0, -2), and the closest point on the line segment (3, 0, 0) from our last blog post, ...

It forms a flat plane in three-space. If we think of the columns of A as vectors a1 and a2, the plane is all possible linear combinations of a1 and a2.

This angle changes as you can see in the picture where a0 is the angle of the velocity u0 we have at the beginning. If someone gives us the angle at any ...

Here we want to shoot a projectile and find if we have hit the target (box). As you can see, the Raycast function takes two vectors as a parameter.

I start by getting them make their own set of 3D axes using straws (and tape/pipe cleaners) which they can then use whenever they like.

After the Statsbot team published the post about time series anomaly detection, many readers asked us to tell them about the Support Vector Machines ...

Math is relevant to software engineering but it is often overshadowed by all of the exciting tools and technologies. In the field of data science, however, ...

Question: So, now you've been refreshed on your vector mathematics, trigonometry, and the physics concepts .

The files posted below are lecture notes from some previous courses that I've taught. I usually update the course notes each time I teach. I post these here ...

Vector images, which are made of thin lines and curves known as paths, are rooted in mathematical theory.

Most of the examples we see on the web deal with univariate time series. Unfortunately, real-world use cases don't work like that.

As we can see that distance will be less going from X to Z when Y is intermediate node(hop) so it will be update in routing table X.

PVector u = new PVector(-3,7); u.mult(3); // This PVector is now three times the size and is equal to (-9,21). Example: Vector multiplication

As can be seen in Fig. 2 (ii) above, the vector \vec{b} is shifted without changing its magnitude and direction, so that its initial point coincides with ...

Predictive models are extremely useful, when learning r language, for forecasting future outcomes and estimating metrics that are impractical to measure.

The line here is our separating boundary (because it separates out the labels) or classifier (we use it classify points). The figure shows two possible ...

Introduction to Applied Linear Algebra: Vectors, Matrices, and Least Squares 1st Edition, Kindle Edition

Yet another one of our temperature conversions. It helps us find temperatures after events such as rain and downbursts. We can also determine what type of ...

For example if you are creating some angle questions for your explanations or for your pupils to practise, then you can use his missing angles generator to ...

Technologies used in meteorology depend greatly on mathematical principles as well as physics. Examples include weather radar, chart usage and ...

Let, \vec{AB} = \vec{a} and \vec{BC} = \vec{b} . Now, considering the triangle ABC and using the triangle law of vector addition, we have

We won't go into the mathematics of lattices in much depth here, but one can think of lattices as a tiling of n-dimensional space

So now I have a second set of calculator revision mats. Again, they have four levels of difficulty so you can pick the right level for your pupils.

As you may have already noticed, vectors are the type of thing that makes us giddy… yep, you can call us design-nerds, WE ARE.

Math has the illusion of being effective when we focus on the successful examples, Abbott argues. But there are many more cases where math is ineffective ...

... set of written problems will be posted later on. The reading is due Thursday, February 14 at 10am. See the assignments page for handin instructions.
