As a Canadian, that actually sucks to see. I really wish we had more advanced math classes and it's the main reason I started being curious about this board. Here we learn the bare basics and it's basically all about remembering formulas and doing textbook exercises. I thought after high school I would do real and fun math but college so far has been even easier than high school. I never opened a science or math related book in my life, I'm pulling through with 90s which could be betters (aiming for 95s next semester). To any Canadians on this board, does university math get better or is it the same garbage high school level crap we have in college?

there is literally nothing more pathetic than people who think learning calculus slightly before other people makes them smart, interesting, clever, etc.

these fucking 19 years olds literally never shut up. thank god 80% of them have a mental breakdown by the time they hit junior year and they struggle for the first time in their academic careers and lose all motivation to continue. because at least by then they quit posting garbage on every forum dedicated to calculus/physics/engineering etc

Why are you arguing about this? It's literally calculus. I learned calc 3 when I was 15 off Google and some old textbooks. Calculus isn't hard or counterintuitive and you're literally trying to one-up each other over who learned what first.

I bet Americans learn about the economics of federal devolution before Europeans but nobody is saying that makes anyone smarter.

This is childish.

This. Every engineer and codemonkey can solve integrals or diagonalize matrices after watching a 5 minute YouTube "How to". That's why Math majors rightfully look down on all other STEMfags.

looks exactly like the shit I would have been doing sophomore/junior year in high school. and yes, these are trivial problems - none of this is actually about learning calculus, it's about learning the tools for it invented by people much smarter than you so you can pass your "weeder" classes for an engineering degree.

A parametric function is defined as
f(θ) = C = < 3θsin(θ), sec^3(θ) >

Point (8,k) exists on C

To solve: Find a value for θ (greater than or equal to zero and less than pi/2) where 3θsin(θ) is 8. Put that θ into sec^3(θ) and get a y value. That is k

[Anonymous No.9744588]

>>9743931
Start by setting [math] k = 3\theta \sin \theta [/math] and use [math] 8 = \sec^3 \theta [/math] to solve for [math] \theta [/math]. I'm also a 3rd year undergrad in math and I only know how to do this problem because I TA low level courses. It's okay to forget trivial shit like this, don't let the europoors get to you.

[math] \sec^3\theta = 8 \implies \sec\theta=2\implies\cos\theta=\frac{1}{2} \implies \theta = \frac{\pi}{3} + 2\pi n[/math]
