    After struggling with this for a week, I said to myself, "Maybe the organic chem guy has a video. He has videos on like everything." Lo and behold, it's the first search result. I'm always amazed by the depth of knowledge and skill on this channel. Infinite thanks from a college student just trying to pass their precalc class!

    Thank you, your videos have been a lifesaver for math this year. Unfortunately the instruction I'm receiving at school this year contains limited examples and my teacher isn't exactly the best at explaining and often tends to jump around on notes which means I get lost easily, plus we're learning a whole year's content in like 9 weeks and it's a cram. Again, thank you so much for making those videos, I love how you give lots of examples and explain in a step by step manner which I really miss
    from last year's teacher.

    22:59 in this problem, can we instead change the right side of the equation after changing the left so that it matches in the end? or will it be wrong because we already chose to do the left to make it equal to the right side? we can change the tan(x) to sinx/cosx and then multiply it to the sinx beside it. that makes it the same to the left side of the equation.

    • @noahgodsonagbele7345
      @noahgodsonagbele7345 2 ปีที่แล้ว +2

      Proving Trig Identities do not have one approach. The goal is to prove the equality of the left and right sides. Therefore, as far as you are able to apply the identities and algebra to prove that the right side is equal to the left side, you should be ok.

    In question 5 it'd be easier if you take the more complex side of the equation and simplify it, I'm speaking this with prior experience and if you do that here is what you get:
    Sin(x) Tan(x) = (1-cos²(x)) / cos(x)
    => Sin(x) Tan(x) = sin²(x)/cos(x) - since 1-cos²(x) = sin²(x)
    => Sin(x) Tan(x) = sin(x) × sin(x)/cos(x) - simplifying the square on sin(x)
    => Sin(x) Tan(x) = sin(x) × tan(x) - since sin(x)/cos(x) = tan(x)

    Is there a rule for the algebra you used at 23:08? Can we use that rule if we had Cos^2x or cosxSinx?

    for number 8, could you also just factor out the sinx out of the fraction?

    I love math, but when I lesson this It seems I want to give up, This lesson need extreme understanding in trigonometric identities and formulas. But when I prove it, I breathe conveniently.
