I am an engineer, i need to perform a cross products for moments of a force, i am also taking a differential equations class and we used matrices to determine if two solutions are linearly independent
it usually isn't covered in basic classes until third year for some reason. when if finally does show up, you are just kind of expected to know everything already.
i know right? my algebra 2 teacher in high school skipped over it saying "you'll never use them" a year later i took the ACT and missed the question because it was on matrices and i only learned how to add equivalent matrices...
Orthogonal diagonalization of a 3x3 matrix takes ******* ages and I don't even know why I'm doing it. With most maths, I know there's a reason behind it, but with matrices I have no ******* clue.
My history teacher had a map in her class to show us which countries invaded which and a bunch of **** like that... doesn't necessarily have to be geography.
If there is a numeral of a lesser value before a numeral of a greater value, then you take the value of the lesser numeral away from the greater numeral, for example..
IV = 4. I = 1 and V = 5, therefore if you put the 1 before the 5, it makes its value 4.
If a numeral of a lesser value appears AFTER a numeral of greater value then you add the values together, for example..
I know man. I used to be like this. First off you have to break the ice and ask for every tiny bit thing you don´t understand. If you don´t get it on first time then ask second time! Then it should go smoothly... Also solving few math problem time to time is recommended too. Nothing big just 3 solved equations twice per week should be enough...
Followed up by,
"We did'n't learn about it last year though, the teacher skipped it."
"Nonesense, it is required learning, you just forgot is all."
"No, really..."
-continues lesson even though half the class agrees-
