Question

1. Given a→=[2,−10 ]and b→=[−8,23] find:
2. 3a−2b→ 
3. a•b→ 
4. a+b→ 
5. projb→a→
6. The angle between a→ and b→

Answer 1

There are lots of Youtube videos and articles (look at websites that are reputable for math). You just need to know what to ask for. To solve these types of problems you need the following topics/formulas:

1) scalar multiple of a vector

2) adding or subtracting two vectors

3) the dot product of two vectors

4) the angle between two vectors

5) how to project one vector on another
