Linear Algebra is used in computer games. How do you rotate an object? How do you make things move? It all comes down to Matrix transformations. Linear Algebra is also used in designing Artificial Intelligence (along with statistics), and an important mathematical tool in
the area of computer security. Linear Algebra makes it easier to solve certain problems, and the problem is more intuitive.
Linear Algebra is also used extensively in engineering, when solving systems of equations, and also has important applications in game theory.


I know it has it's purposes, but not everyone wants to get into fields like game programming or theory, etc.

And if you struggle too hard against learning it because you "don't need it," that's an early taste of what it's like to get old and not want to learn new technologies. Scary if put that way, huh?

Try to focus more on either that it's required and so you will do it, or ideally find ways this stuff could be useful, even if not in your expected career path. Dwelling on how something is useless and boring is a surefire way to prevent easy absorption and keep yourself stuck in math class.




This right here, is that stuff I'm talking about, (for example). I do NOT need this stuff for my path of life.

Ultimately, it should be a decision to your own self if you want to go on in mathematics. My father has a degree in advanced engineering, and if I came to him today with something like this he wouldn't even know where to begin.


-An infinite area integral
I don't know
-The quadratic formula

It helps you think better.

just like not everyone is interested in computer science/engineering/physics/math/statistics/working in banks/insurance/etc
though even if you're not interested in those, it's still a pretty useful tool, like a calculator.

Math is fun. And an incredibly efficient GPA booster (Thank you, Intro to Stats!).

Rather that than any English-related class

I'm the opposite. Give me all the English, writing, and philosophy classes. Math is hell.

Your dad has a calculator to do that for you. It is good to understand what your using. I use all of those things quite often. In fact those are all things I learned in High School.

The first is the integral of e^(-x^2) from - inf to + inf. Very simple stuff, used in everything from making pipes, to building cars, to making everything we know today.

The second is just the slope and curve of a line. Would be useful for whatever it was designed for.

The last one is to find the roots of a squared function. Very simple. Learned in High School Algebra.

For your path of life, you may not need it... I use them frequently in things such as finding the concentrations of all minerals in a water sample, finding theoretical oil, the flux in the atmosphere and everything. Everything we have now-adays is based off math like this (except much, much more advanced!) I am taking Higher Mathematics for Engineers 2 (Differential Equations 2 on steroids pretty much).

Also, what kind of Engineering is your dad in? My dad was a Computer Engineer and he remembers all this math and more than I do after 30 years! I would be surprised an Engineer forgot such basic math.

The second one is the Fourier Series Equation, to be exact since slope and curve of a line could be anything.

I agree with you to some extent, not all math taught in school is used. But it's good theoretical knowledge and a way to train yourself some kind of organizational thought. I'm sure if you looked for an application, you'll find something.

Since I'm planning on running through some form of chemistry, math is going to be vital to my career. Hopefully I can figure out why I never get the right answer when I follow PEMDAS.

PEMDAS won't save you with this crap.

Math teaches you problem solving skills. It's good to be generally taught in it.

The way they teach math is shit, like all other public school education though.

However, math is very important, not in the way you need to use formulas in your job, but the way you approach problems.

I remember thinking imaginary numbers were the stupidest shit back in 9th grade. Then in Differential equations...they showed us how to use imaginary numbers to solve real world problems.

It blew my fucking mind and I loved it. I mean c'mon, using imaginary numbers to solve real world application problems!? Like how the fuck is that not cool!?

Ahh, thanks for the name! Rec the formula, didn't remember the name! Same for the last one!

the only math you need is abstract math

Math is very important no no doubt, but I feel like much of my time in high school was wasted learning certain types of math that I will never use. I feel like that time could have been better spent teaching us basic life skills that we need for adult life. Oddly enough I found "Logic and Set Theory" to be interesting to me, and I had an easier time learning it than the other types of math I was taught.
