Law of sines

  1. Aug 23, 2011 #1
    sin α/a = sin β/b

    when my isolates b they get

    b = α sin β/sinα

    I would think to isolate b you would multiply both sides by 1/sinβ which would make

    b = sin α/ a sin β

    Take sin α/a = sin β/b.

    Multiply both sides by 1/sinβ and you get

    sin α / (a sin β) = 1/b.
