Yes

If you do NoChan, sleep well, eat well, and spend +6h a day solving problems (take ADHD pills if necessary), then it shouldn't be too hard. Precalculus is just an odd mixture of Algebra, Trigonometry, and a bit of Analytic Geometry.

easily

You can do it. Just STUDY. Don't get distracted. Keep you puter and phone away at all times when stoodying.

Forced rote learning like that can be hard to do a lot of in a short period and remember it all on exam day. Along with just studying normally I think it's important to actually think about it too when you're not studying. Like when you're driving in your car try to solve some problems in your head or recite definitions of things you need to remember. I found that help me and it sounds obvious but when I thought about how I'm thinking while studying I realised there was a lot of time I could be thinking about it when not sitting in front of my textbook and I think it also helps to make it stick in your brain more

Thanks for the advice, I will try to dedicate 8 hours a day to it, leaving 4chan and cell phone.>>15059605

Get a psychiatrist to prescribe you Adderal too, and stare at a wall or take a walk outside whenever you need a break.

You need to be 18 to post on 4chan

I don't use drugs by globohomo

>>15060943
23 age my fren

>>15059042
You could do it in 2 weeks, no?

>>15060741
Very based. Wish you luck fren

gesel?

>>15060947
It's not globohomo approved which is why its a controlled subtance , smoothbrain.

yeah, probably sooner
also don't use that book
Axler has better book

just study functions and how to do algebra on them. Like properties of log, ln, e^x, a^x, sinx, cosx, tanx. And study the unit circle and study basic properties of sin and cos.

I never took any precalculus/trigonometry course in my life. Turns out the above mentioned was all that was needed.

For example, suppose the fundamental equation sin^2(x) + cos^2(x) = 1. Turns out you can derive most of the other identities needed for calculus from that one. Like if you want the formula for sin^2(x) = 1 - cos^2(x) then subtract the cosine part from both sides. Similarly, try dividing through by cos^2(x) and you see that you get tan^2(x) + 1 = sec^2(x). similarly if you divide through by sin^2(x) you get 1+cot^2(x) = csc^2(x).

Now you wont need much more than that regarding trig identities. Now for trigonometry more broadly. Again I never learned it but what i did learn is that I can construct triangles such that I can use SOH CAH TOA that give me the values i need for angles I need. By exploiting that cos is even and sin is odd. i.e. cos(-x) = cos(x) and sin(-x) = -sinx.

So figure out some triangles so that theyre 1) a 30,60,90, and 2) 45,45,90. Then take the formula to convert between degrees and radians and verify that 30 = pi/6, 60 = pi/3, 90 = pi/2, 45 = pi/4. And then use SOH CAH TOA to make cos,sin of those angles in radians. And then use even and oddness of cos and sin to add/subtract multiplies of pi radians to those basic angles, and figure out how to fill in the rest of the unit circle.

You only need to do this stuff to a basic degree so that you can evaluate limits, derivatives, and integrals. you dont need the stuff to actually "do calculus"

I think using some youtube lectures would be a good alternative if you have less time and just solve some IMPORTANT problems in the books after you watch a lecture of particular topic

they ask students to do difficult and completely useless tasks to identify which ones are servile idiots ready for a life of being an exploited loser in a cubicle, it works surprisingly well

might help to spend a few days brushing up on your basic algebraic manipulation skills involving the distributive, associative and commutative properties. Lots of people I've tutored know how to do operations but they don't really remember why they can do them in the first place, and that leads to a failure to recognize that math is about putting forth logical arguments, not just algorithmically recovering an arbitrary solution
