    I’m a 39 year old who does nothing related to any of this. I did well in languages and literature/philosophy, etc, but struggled in science and math. I have absolutely no reason to be here but suddenly I’ve been utterly fascinated by math and science. I’ve been studying the Bible and ran across Chuck Missler who was brilliant in both science and theology and now I want to know all about the mathematics and sciences God created. And you know what? Suddenly it all makes sense. This teacher is one of the absolute best!

      Hi, 41 here. I’m back at college post bachelor’s (‘07) to study physics for a radiology program. I agree with you and this teacher is amazing.
      The Bible is a good read. So many people pretend to be religious but have never actually read the book.

    tip to remember the essential trig functions is to remember the term "SOH CAH TOA".
    SOH = sin (opposite over hypotenuse),
    CAH = cos (adjacent over hypotenuse),
    TOA = tan (opposite over adjacent)

    EASY WAY to remember these relations is to just memorise the word SOHCAHTOA. Sine is opp.over hypotenuse (SOH) - Cosine is adj. over hypot.(CAH) - and Tangent is opp. over adj.(TOA).

  • @georgeseese

    Another excellent video. However I have a question. Your explanation of vertical and horizontal makes sense for computing force vectors that we're familiar with e.g. throwing a ball. But when thinking of triangles in general, a given triangle can be displayed in many positions; most of them have sides that are not vertical or horizontal. And the sense of vertical and horizontal does not apply in all cases. Also, when focusing on one of the small angles, its opposite side is not the opposite side of the other small angle. Shouldn't this general viewpoint be considered also? I apologize if you cover this in another video. You are gifted to explain so many subjects. Many thanks!

    Inrerstingly enough, the relationships between SOH, CAH and TOA are the same as the relationships between E, I and R in Ohms law. Same with C, pi and D. Because of that, I like to put them inside a bubble or pyramid just like we do for Ohms Law for a visual reminder.

    thank you for this!!! non trad student going back to college and need physics. This is a general question, for the most part, in an alg based physics class, is this the majority of trig that will be used in physics? like If I can grasp this, most if not all of the trig someone will use in alg based physics will be comprised of this? I am only asking as I dont want to take trig just to take phys... if i know I can get this, I can be somewhat comfortable knowing theres not this massive amount of trig I am not away of! thank you and i do mean in the general sense... if this is 85+% of the trig I need, I would feel good to go.

      The calculator will give you the sine/cosine, other wise you have to look it up in a special book called an index. This is why modern calculators are so great. Imagine doing physics with an index!

    • @MathAndScience
      @MathAndScience  2 роки тому

      I hear your frustration but you cannot really do it without a calculator. Before calculators textbooks were filled with tables in the back of the book where you would calculate the sine and cosine or the inverse sine in the inverse cosine. Also slide rules existed which if I’m not mistaken could allow you to calculator but that’s just a type of calculator as well. This is why we focus on the special angle such as 30° 60° 45° 90° and so on because those are easy to remember but other intermediate angles you’re just not going to be able to do without a calculator unless you have a super human memory.
