Many variables and complex connections lead to multivariate calculus. There are some good ideas in here. I am not even surprised to see so many applications.

So is the cost of a Starbucks coffee dependent variable: I think the most interesting things are not totally linear -- real life data that might be KIND of linear. This is called multivariate calculus because, multiple variables.

If you are impressed with the list you have, just know that for mathematicians, your list is a sub-point in one of my lists. Mathematics have the power to make me think of very abstract things which allows me to solve so many problems.

I am not interested at all in applications. If more roads are built, capacity goes up good for business but quality of life goes down.

Sociologists and politics majors ought to know linear algebra to think about problems like these. People move away, which results in more traffic, which results in less excess capacity, which is bad for business.

Linear algebra deals with vectors, matrices, and tensors, and how to operate them with each other so that everything makes sense and is useful. Philosophy concerns the real world, even when it is abstract. His video with the escalator really gets it right.

At some point, you lose interest in explicitly solving problems i. A simple every day thing The number of papers in the waste basket against number of bad ideas is probably not as interesting.

For the mathematician Linear algebra is of course a rich field in its own right but I wanted to write a motivating explanation to aspiring students who do not yet know what it is and how it is relevant to their lives.

So as they create equations that can best fit the data some time perfectly like with concert tickets, often not perfectly because of data measurement, etc -- they can interpret what the model actually means and use it to make conclusions and predictions.

Certainly, such a list belongs in the answer of "why study ? Meaning of "Linear" and why it is "Easy" Since you are asking the question, perhaps you would benefit from a discussion of what "linear" means, and why it is "easy", as mentioned in some answers above.

An object moving away is interesting link to computer graphics! Many great mathematicians have used instances from physical sciences as motivation for math, for the sake of understanding. They also use logs. As are things like Voltage vs current and resistance.

If you are interested in this at all, that Dan Meyer clip is really great. You can invent some econ problems--make cost and revenue linear and get students to computer profit or something along those lines.

Anyhow -- thanks for all the answers. How long does it take light to reach us from Pluto?

This corresponds to a change of basis in linear algebra, which naturally pops out the centrifugal force and the Coriolis force from your force expression. Okay, you said distances of cars from home is boring, but Because if there are no limitations on what the independent variable can be, then all patterns are linear as against something.

The tools that they have are the linear model, the quadratic and the exponential.Jul 21, · Linear Relationships in Real Life?

July 21, AM Subscribe I am redesigning a high-school Algebra course so as to make it more meaningful to the students. Solve various word problems that involve real world relationships that can be represented by linear equations or functions.

Real world uses for linear functions include solving problems and finding unknowns in engineering, economics and finances. Real-life examples of linear equations include distance and rate problems, In a linear relationship, two variables or quantities are proportionate to one another.

As one variable changes, there is a constant rate of. Real-life examples of linear equations include distance and rate problems, pricing problems, calculating dimensions and mixing different percentages of solutions.

One application of linear equations is illustrated in finding the time it takes for two cars moving toward each other at different speeds. I don't remember life without linear algebra, and I don't want to live without it ^^. It is so incredibly useful to a mathematician, and to many applied sciences, there is just no way around it.

Here are some of the real-world relationships that are governed by linear equations and some of its applications: Load and displacements in. What is an example of a linear function's real life situation? Update Cancel. Now, there is a linear relationship between the money you spend and the number of packets you buy.

More explicitly, A=20N, where A is the amount of money spent and N is the total number of packets bought. What is an example of a function's real life situation?
