No.
>what is pre-calculus
Only pre-calculus you need for calculus is a basic understanding of trigonometric functions and limits. The other topics they will cover before you go into (parametric equations, vectors, and matrices).

kek look up The Chinese Room.
you can easily do calculus without understanding it
it's just mindless applications of rules
it depends what you want to get out of doing it

Well, this is the only appropriate time to solve them at all, so he did good. If you waste your time on this shit in uni, you have chosen a terrible programme.

I don't know but I'm starting to believe that the best way to learn math is via programming.

Read a text book, every paragraph write it in your own words until you understand the 'story' behind whats happening.

If you don't get it pick a different source. Use different sources and repeat until you understand whats going on..

Then learn python or someshit and code up a differentiation function or approximator. Then start playing with it.

Forget doing math by hand, simple mistakes are too common and steal away the 'soul' of math and replace with how many symbols can you write without accidentally fucking up. Which is more akin to a bricklayer's job (how many bricks can you lay without fucking up).. then actual intellectual work.

Precalculus is our personal torture chamber perfectly designed for brainlets. In it we waste their time teaching them to manipulate a bunch of functions that are supposed to be "special" instead of teaching them the concept of function properly, which would allow them to learn any particular function on their own should they need to. These special functions we teach them also depend on other abstract concepts like irrational numbers, which are also not properly explained until calculus, so if you are a brainlet you are essentially fucked and I hope you know that we are playing with you. Precalculus is Auschwitz for brainlets.

Seems like Calculus II is Auschwitz for brainlets but it might actually be college algebra since that class has the highest fail rate of any college course probably follow closely behind by precalculus.

Well, certainly calc 2 is "harder" than precalc, but I'm talking in terms of pure PURE brainlet torture. But you are right, college algebra is the true Auschwitz. I sometimes forget that the king of useless mathematics taught to children and "adults" is analytic geometry, given that once you enter a real math classroom you learn that all of manalytic geometry is just one equation with matrices and quadratic forms that we memed up into an entire year of material just to mess with the brainlets.

I still think it is quite cruel to teach people about special functions and irrational numbers in the course that is pre- to the course where they will actually learn proper function theory and real numbers. Pure madness. I love how all of math is just made to fuck brainlets in the ass.

Mathematician here with teaching experience. The point of geometric problems at school is to instill the culture of proofs as well as deductive and inductive reasoning. Most if the things you are taught in school/college are pointless, they are there so that students learn how to learn.

You use the word "brainlet" 2 times but if you couldn't understand this point on your own, then I have some bad news for you regarding your relation to brainlets.

Pre calc in my experience just laid foundations in algebra and trig you would need to prepare for calculus. Trig identities are solid to know for making integral calculus managable. I learned partial fractions in pre calc and they came up in stuff like calc 2 and diff eq, mostly if your algebra and trig are solid, calculus through multivariable is fine. The actual calculus taught is easy enough to understand, it is just getting your functions in a form to work with using calculus is the real trick.

Difficulty is relative. That said, for calc it's very exaggerated. In the U.S. I notice among older folk it has the reputation of "Hell no I never took that, it's way too hard", but with people my age it's more like any other class. There are a few things which stagger students like integration by parts or the various integrals you must memorize, but I feel the public perception that it's some dark art for intelligent people only is thankfully vanishing. It really surprises me how successful my parents' generation was when the educational standards were so much more relaxed by comparison.

You really can't fathom how dumb american public school students are if you have never experienced it first hand. The most incredible things will come out of people's mouths, and every effort is made to accomodate their faggotry from overemphasizing applications, which of course robs them of ever developing intuition and the ability to do abstract reasoning, and also simply teaching to the test. We literally train our students how to pass standardized tests and the teachers will purposefully tailor their courses to achieve certain test scores as funding depends on the relative average scores of students compared to those of the surrounding schools. I don't agree with what he said regarding analytic geometry, if anything we deprive people here of proper visual stimulus learning math and science despite again over emphasizing "visual learning" while not actually teaching people to visualize anything properly.

This so much. Wtf is with all the retards ITT who think that like one or two specific concepts are the only important parts of precal? That class is supposed to reinforce the algebraic foundation that calculus is to be built upon.

Isn't the purpose of calculus lost when people just try to solve random, complicated functions?
They treat it like it's a puzzle and it feels more like a very cheap way to get that rush of mathematical success.
But maybe there's a purpose I don't know about, I've only done Calc 2 for prereqs.
