# Question #960ba

Oct 16, 2017

You would use the same process to resolve ${\hat{a}}_{x} \text{ into } {\hat{a}}_{x} ' \mathmr{and} {\hat{a}}_{y} '$
that you used to resolve
$\hat{a} \text{ into } {\hat{a}}_{x} \mathmr{and} {\hat{a}}_{y}$.

#### Explanation:

I assume you mean to resolve ${\hat{a}}_{x}$ into a different reference system with axes x' and y'. You would need to know the angles between ${\hat{a}}_{x}$ and the axes x' and y'.

Then you would proceed with the steps that you used to break $\hat{a} \text{ into components } {\hat{a}}_{x} \mathmr{and} {\hat{a}}_{y}$.

You would ignore what you know about $\hat{a}$. Consider ${\hat{a}}_{x}$ as your starting point and follow the process for resolving a vector into components parallel to the axes of a reference system.

I hope this helps,
