    guys if ur confused when to put sin on top or bottom, when you're looking for an angle sin is on top, when your looking for a side sin is on bottom of the fraction. Hope this helps

    0:05 "The Law of Sines can only be used for non-right angles triangles"

    I don't know if you're gonna see this comment but I have a question about angles. You explained at 1:45 that the relation between an angle and the opposite side is so because if the angle were to change, then the side would change.
    My question is, wouldn't everything change? Not just the "related" side. So is there another reason why the angle is related to it's opposite?

    You're doing sin95/sin10. There is no "sin" before the 10. It's just sin95/10
    Hope that helps! :)

    It's such a shame that I ended up with a C in trig. One of my problems in that class was that I did not really understand my professor due to her accent and the way she would over-complicate explanations of certain concepts. I was also kind of intimidated to ask questions during class because I felt like others didn't have the same problem. Fortunately, I'm in precalc and so far I've aced my exams and quizzes by doing my own research outside of class and my textbook. Thank you for this easy and sensible explanation!

    its supposed to be 10 x sin35 / sin95
    NOT 10 / sin35 x sin95
