# Insert new line between a bracketed formula

Hi, i want to break a long formula among multiple lines but its enclosed within a bracket and i am unable to break it. Formula:

{c} rsub {x} = sin(a0)*(cos(a1)*(a0 + a0*sin(a1) - 1.0*d1*cos(a1)) - 1.0*cos(a0)*(d1*cos(a0) + a1*sin(a1))) - 1.0*d1*cos(a1)

I would like to add a newline in between the formula so that it spans in multiple lines. How should i do it ? Please help
