You need Trig for Calc and Diff Eq so it's gonna be an uphill battle but manageable.

Trig is the hardest parts of calc. Getting an 80 self taught isn't that bad

Learn it now, it only gets harder. Cakc 2 you learn polar co-ordinates. Calc 3 was 60% finding surface areas and volumes of spheres, cones, cyliners, etc. Then flux integrals...

x = rcostheta
y = rsintheta
dxdy = rdrdtheta (iirc)

That's high school courses. In college it goes College Algebra -> Precalculus -> Calculus

No, that's what everyone who isn't a lazy brainlet does.

>>trig stuff still fucks me up sometimes
Normal, you get better at it the more you use it in calculus and beyond.

Trigonometry is so easy when you see what it really is. It's a joke, frankly. It's just taught in an awful way. Even "SOHCAHTOA" is just super dumb. What a covoluted, weird way to teach something so simple.

Just self study trig again to make sure you're good
its quite easy, much easier than geometry, just remember the elementary sines/cosines/tangents

Same here man. I started on math 115 then 125, geometry, trigonometry, precalculus and now Calculus. And Trig has been the hardest math class I’ve taken. Even calculus right now is easy in comparison

SOHCAHTOA reminds me of Krakatoa. Just remember like that. It's easy once you know the words.
sine = opposite / hypotenuse
cosine = adjacent / hypotenus
tangent = opposite / adjacent

Trigonometry is precalculus. Read the trigonometry sections of Stewart's Precalculus book. If you're not a brainlet and are willing to put in multiple hours a day you can easily cover all 3 trigonometry chapters in 3 days.

Standard American way of doing it is:
9th grade algebra 1
10th grade geometry
11th grade algebra 2
12th grade precalculus (which I believe is mostly trigonometry, might also cover some algebra, and likely covers vectors, matrices, etc a bit too)
first semester college: calculus 1

Of course that progression is for brainlets. I took algebra 1 in 7th grade, geometry in 8th, algebra 2 in 9th, ap calculus in 10th (skipped precalculus kek)

Oh and to directly answer your question: The brainlets take algebra 2 in 11th grade (that's the standard, and normalfags are brainlets). The ultra-brainlet way is for people who are behind a year in math to take algebra 2 in 12th grade. The ultra-ultra brainlets are the ones taking """college""" algebra.

You don't even have to memorize muh sohcahtoa memefaggotry if you understand the most basic part of trigonometry. Sine is the y function, cosine is the x function, tangent is the ratio of the two. So naturally if you have a triangle positioned in the unit circle, sine will be the y-value which is opposite ?, and cosine will be the x-value which is adjacent to ?, and tangent is their ratio, and the 'over hypotenuse' is just if the hypotenuse isn't 1 to account for it not being in the unit circle.
Don't memorize this faggotry, just understand why the stuff works the way it does.
I get triggered to no fucking end by the 'All Students Take Calculus' mnemonic. It's so much harder to memorize what that means than to just understand why a given function is positive or negative in a given quadrant. Fuck mnemonics, fuck mathematicians, fuck textbooks, fuck math teachrs, fuck academia, fuck school, and fuck the jews.

It is in both the precauclus books I have been using (Stewart and Bitlzer). "All Students Take Calculus" as in, start in quadrant 1 going counterclockwise, A S T C as in All, Sine, Tangent, Cosine. It tells you which function(s) is/are positive in which quadrant(s).
