Vectors , Simplfiy its form and express

[learner123]

Hi Everyone,

I am still doing my exam revision questions, and I am having doubts my workings out are corrected, on this question. Well let me explain the question it is Question 10. Well we know they're three vectors here: a/hat, b/hat, c/hat.

We know we need to use the i and j , represented x and y. I did the working out on my paper to its simplest form.

Please tell me, If I missed out on any step I should of taken.

Kindest Regards,

Looks good to me - except on the first line for 10 (iii), you should write vector_c as 6i - 9j. You have the following work correct.
