express in a symmetrical form $\displaystyle \frac{a}{bc}+\frac{cosA}{a}$

basically i don't know what is meant by "symmetrical" since this is a triangle.

the book did not give an example of this but think it was in the book prior to this Adv. Trig

the answer to this is:

$\displaystyle \frac{a^2+b^2+c^2}{2abc}$
