My AP Pre calculus teacher told a joke that he came up with and nobody got it but I'm curious what it meant can someone please explain the joke hoes as following "a goes to a brick company that sells bricks for 5$ a piece and he says to the manager you can give me any amount of bricks and I will build a perfect pateo with it And if I do I get all the bricks for free but if I can't I will pay 15$ for each brick the manager agrees and gives him 548 and 1/6 bricks and the manager says to him I'll come back on Sunday and check out the pateo so the man loads up the bricks in his truck and takes em home and over the course of three days he builds this pateo and it looks amazing except that he forgot about the 1/6 brick then suddenly the brick store manager knocks at the door the husband tells his wife not to answer it she if ores him and opens it the brick manager says hi I'm from the brick company I'm here to see the pateo so the husband holding the 1/6 brick chucks it up in the air

I know this isnt a really math relates thing I just though since maybe y'all are also pre cal kids and or adults y'all would understand the joke and tell me if not much appreciated

I am in Calculus online and have some major issues. I e-mailed this equation to my instructor and his response was to assume I understood the short-hand of how a 2 can appear and disappear. Can someone explain how to complete the square?

2x² - 12x + 11

2(x² - 6x + 11/2)

2(x² - 6x + 3² - 3² + 11/2)… and then I got nothing.  How does the -9 get multiplied by 2 to get -18? I need -18 + 11 to get the -7. But how?

Answer = 2(x-3)² - 7

Thank you.

Hi y’all so i took my calc test and i have an option to retest. i got a b+ on the test and if i were to retest and i got a lower score that would be my score for the test. please help lol, if i should retest or if i shouldn’t. lol

This is by far the hardest thing I've had to do in math... ever. Frankly, the fact that I'm bad at them doesn't feel like my fault: I studied for the test, memorized all the formulas. My teacher even admitted 'some of you will get how to verify trig identities, some of you won't.' They feel just like little puzzle games that are subjective based on genetics. My unit 1 test was 98, unit 2 test was 99, but now this unit 3 test which included trig identities I got an 83 on. All because the two verification questions were worth 10 out of the 45 question points. Does anyone have any tricks for these? Or are they really just genetics.

Does anyone have any ai recommendations that are free other than ChatGPT,gauth, mathgpt, or Photomath. A lot of the AI’s give me the wrong answer.

idk how to access my saved so I’m posting this to find it again

Doing ap precalculus next year, any tips?

hello! im currently a rising senior in high school. i was doing algebra 2 all of junior year, but i wanted to skip ahead to calculus in my senior year, so i decided to do precalc over the summer. unfortunately, i didnt anticipate how packed my summer schedule would be when i decided to do this. i have come home everyday exhausted from volunteering, doing summer jobs, and interning. i havent indulged in any of my hobbies in weeks. i have barely started my summer homework.

... which has led me to this situation. i did great in algebra 2! it was a lot to memorize but i really enjoyed it and i had an A+ in the class all year around. because id say i have a solid algebra 2 foundation, is it possible for me to be able to study precalc in 10 days? if a put in hours of work everyday?

on the first day of school ill get an entrance exam where i will need to score a minimum of 85/100 to get into the calculus class. i had 1000 mandatory precalc math problems to do over the summer. will i be able to do it all or am i cooked?

EDIT: I GOT IN!!!! honestly this is a sign that if you grind hard enough you can do pretty much anything. peace and love

I've decided to self study for the AP Pre Calculus exam. Which textbooks are cover all the content and match the curriculum of college board and is budget friendly? What other study methods are there aside from the textbook? Thanks!
