Vectors: write 3 operations on 2-D vectors, 4 on 3-D; find u

[asimon2005]

2. Write the 3 operations on 2-dimensional vectors.
3. Write the 4 operations on 3-dimensional vectors.
4. Write the 4 ways to write a vector.

9. Find a unit vector with the opposite direction to a= -3i+2j-4k

12. If b is a 2-dimensional vector with magnitude b=3 and direction theta=153 degrees. Find the components of b?
Thanks in advance.

Re: Vector sheet



Hello Asimon:

At the top of this board's index, you will find a post titled, "Read Before Posting".

Please, read it.

It outlines your responsibilities for seeking help at this web site.

The main points of that post are (1) we don't simply guess at lessons to provide solutions for your homework, and (2) you make it very difficult for people to help you when you withhold your knowledge and attempts.

After you read your responsibilities, then please come back and show us what you've been able to accomplish so far on these exercises. It would be even better if you could also include statements about why you're stuck.

Cheers,

~ Mark
