What shall I know before starting vectors and matrices? (Idk calculus but I know trigonometry)
+209 You should know algebra(...)and it really depends on the person. I would suggest finding that topic on khanacademy, watching the vids, then going back if you have trouble.
+209 here Let me send you the links(you don't have to go in them.... It's fine..)(and also, don't freak out cuz it says precalc, It's just the label... I learned this before algebra1 so the labels are kinda off sometimes...):
Matrices: https://www.khanacademy.org/math/precalculus/precalc-matrices
Vectors: https://www.khanacademy.org/math/precalculus/vectors-precalc
Yes! i use khanacademy! , Lol I already freaked out when i saw "Pre-calculus" :DD
+209 I know... But the weird thing is, Precalculus varies from people..... Some think it starts when you learn sigma, others matrices..... I think it's just Khanacademy's thoughts.
