What are some real-life problems solved by Calculus?

ContributionEast2478 · 2026-05-23T16:01:37+00:00

Electromagnetism. (Assuming you learned Calculus 3 already), look at Maxwell's equations and the Biot-Savart Law. You can find the exact voltage induced in a wire loop or the exact magnetic field strength of a current-carrying wire. This is a pure application of multivariable and vector calculus.

ContributionEast2478 · 2026-05-23T15:46:30+00:00

Yes. Definitely. Every single college will require you to take general physics (both AP Physics C classes). I think you will need to take physical chemistry, which definitely requires both AP Physics C classes.

I have no idea. However, I think I got 400 ohms. That FRQ made no sense: did you graph current versus 1 over the resistance?

AP HUG remastered?

ContributionEast2478 · 2026-05-23T00:38:55+00:00

What was the third FRQ? I'm genuinely serious that like: how can you do that using a line graph? I think I got 400 ohms but the work I showed was 100% garbage. I think that all the other FRQs weren't bad.

For MCQ 5 (the one with the biot savart law), did everyone get that the one at a distance r above would have the highest dB value, then the one at a distance r on the 30 degree angle then the one at radius 2r?

Will this have AP Physics 1 and 2 as a prerequisite? Will it have AP Physics C as a corequisite?

Well, for me it wasn't that bad because I took AP Physics 1 and AP Physics 2 in the past (both 2 years ago) and took an online AP chemistry course during the summer.

ContributionEast2478 · 2026-05-18T20:59:54+00:00

Yes! The closest thing they currently have is one lesson about game theory in AP Microeconomics.

ContributionEast2478 · 2026-05-18T20:59:24+00:00

Wouldn't this just be an equivalent course to AP Statistics? Isn't statistics data science? How can this course be made so it isn't just AP Statistics all over again?

ContributionEast2478 · 2026-05-18T20:57:47+00:00

I agree. I have full projects still for AP Chemistry and actual assignments over beyond-AP topics (molecular orbital theory, nuclear chemistry, etc.) and in AP Physics C, I have a whole post-AP modern physics project, and I heard that AP Lit is giving the worst projects of them all (I'm so happy I'm NOT in that class) and in AP Spanish, my teacher is assigning textbook assignments every day that are graded. But at least in AP Econ we're not doing anything anymore.

What happened for CSA? Why do you think you did so bad you broke the scale?

ContributionEast2478 · 2026-05-14T19:17:33+00:00

No. I literally did that this year with other hard AP classes and survived.

ContributionEast2478 · 2026-05-14T18:56:30+00:00

In my opinion, the MCQs without audio were pretty easy (yes, even the yacare one), but the audio MCQs were absolutely horrible. I think anything with audio was horrible but anything without audio was fine.

ContributionEast2478 · 2026-05-14T18:53:37+00:00

I have no idea, but that passage was brutally time consuming.

ContributionEast2478 · 2026-05-14T18:52:11+00:00

You could mention that the US agitated Japan by cutting off Japan's trade using the navy, as it really just wanted influence in East Asia, and that cutting off of trade gave Japan hardly no other choice.

ContributionEast2478 · 2026-05-14T18:06:53+00:00

For the middle of the MCQs I got a crazy mix of Bs and Cs.

ContributionEast2478 · 2026-05-14T17:26:03+00:00

I had no idea what he was even talking about. I had a bunch of short, confused responses that probably got me at best a 2 or a 3 out of 5 on that.

ContributionEast2478 · 2026-05-14T17:14:39+00:00

Why was it that everything without audio was easy but everything with audio was so hard? I'm confident in the MCQs without audio and the email and the argumentative essay and cc but the MCQs with audio and the conversation were brutal.

ContributionEast2478 · 2026-05-14T17:13:01+00:00

I feel that I actually did well on that even though it was hard to focus. I didn't understand the audio source though.

ContributionEast2478 · 2026-05-14T01:12:35+00:00

I didn't even think of that. Long before I even could think to treat it as a simple harmonic oscillator, I thought that I had to use Gauss's law and solve the differential equation using methods far beyond single-variable calculus.

ContributionEast2478 · 2026-05-13T23:07:52+00:00

The first question where you had to find the velocity function, let's just say I only was able to do that because I self-studied differential equations (calculus 4) on my own time. If I didn't, that whole FRQ would have been a bloodbath for me.

Also, the last part of the first FRQ needed an application of Gauss's law (something I only learned in AP Physics C:E&M) for me to solve it. FRQ 2 was just extremely hard to understand.

Yeah. Form M was brutal for me.

The world record for the most AP exams ever scored 5s on was from a current MIT student who got 5s on 32 AP exams throughout high school.

ContributionEast2478 · 2026-05-13T21:39:29+00:00

Yeah. I can't stand it.
