The standard normal distribution could help you figure out which subject you are getting good grades in and which subjects you have to put more effort into due to low scoring percentages. Once you get a score in one subject that is higher than your score in another subject, you might think...
mathematics is focused on the end point: the answer, the solution, the proof. We attach so much emphasis on the destination — the more efficient the better. We place such high value on the final moment of the mathematical process; this is reflected in the language we choose to define ...
What I would call "the railroad method". If your entity is grounded, keep track of the point it's grounded on, associated with an edge of a specific wall. This requires the different edges of a continuous floor to be linked by some metadata. In this method, it's OK if the entity s...
Let’s say you were given afunctionlike f(x) = x2– 2 (or, equivalently, y = x2– 2) andasked to sketch the graph on the Cartesian Plane. In order to solve the problem you need to: Choose your x-values to input into the formula. Usually you’ll want to choose integers (whole...
In one of ourMake Math Moments From A Distance webinars, we used Day 1 of ourShot Put problem basedunit to help us model the processsynchronouslyby first by asking participants to watch this video and write down anything and everything they noticed and wondered in the chatbox. ...
The point at infinity is then mapped to z=1z=1. If we put z=1−ϵz=1−ϵ, then we see that ϕ(1−ϵ)∼ϵ−2ϕ(1−ϵ)∼ϵ−2. Since g(x)g(x) has an expansion for large xx in powers of x−1/2x−1/2,this becomes an expansion is positiv...
Don't rest and don't put your head down. Use this valuable time to double-check,even triple-check your work. Remember, evenonequestion missed will bring you down from an 800—you need to achieve perfection. What's the best way to double-check your work?I have a reliable method that ...
Not a function: “one to many“. In other words, let’s say you had one x-value that maps to many y-values. For example, — in coordinate notation — (2,1) and (2,10). If the first number (the x-value) repeats, then you do not have a function. To put that another way,...
Ahomogeneous polynomialis a multivariate polynomial (i.e. a polynomial of more than one variable), with all terms of the same degree. Another way to put this: a polynomial is homogeneous of degreedif it is alinear combinationof monomials of degreed[1]. ...
