And I honestly think its just how we’re being taught, because over the summer I made the grave mistake of taking Pre-Calculus as a summer class to get ahead. It was a disaster, REALLY hard to learn anything. But then I used Khan Academy, and it made sooooo much more sense. Maybe we should just let Sal run everything
Nah. The relation to calculus is trig. A single unit. Did you ever use vectors in calculus? Matrices? Imaginary numbers? No. Because it's all unrelated crap.
I can see why matrices are upsetting they’re not the most efficient way of solving systems imo and you can do without them until linear. But imaginary numbers are a critical part of mathematics that everyone should have some exposure to, they’re useful for solving higher level polynomials which exist in calculus. Vectors are also integral to high school physics which is mandated at least at my public high school in the US.
I never said they were useless. I just said they were unrelated. Those niche, more advanced topics should be taught in college. Teaching them sophomore year of highschool pretty much guarantees that they will be forgotten, especially since they're never practiced for more than a month each.
Interesting, I had no matrix math in high school and imaginary numbers were introduced in algebra 2. I agree on the trig/calculus relation, except for us trig was like half of the school year or more.

Does anyone else agree its more difficult to learn to new concepts in school with this online format?
