    If anyone is wondering what the functions actually are, rather than just how to to calculate them, they're ratios. For example, 5/10 = 0.5 is essentially saying that 5 makes up 50% of 10. Likewise, for SIN as an example, it's basically saying the Opposite makes up result% of the Hypotenuse. In her example of sin, Nancy has it equal to 4/5. This means that the length of the opposite makes up 80% of the length of the Hypotenuse. This of course applies for all the trig functions.
    If you want to know what they're used for, Nancy did another awesome video explaining it here:

    During 1990, i spent so much time trying to understand this because although i was told how to use Sin cos tan etc but then i didnt know if sin represent an specific angle with refrence to the right angle or is this ratio of angles.
    My teacher unfortunately was not intrested in teaching during the regular classes at school as much as he would teach at his home for a tuition fee.
    Today this small video gave me the answer.

      @Lanefasts 5 лет назад +15

      She’s writing backwards on a clear surface… You can tell because her body is not blocking the text when she overlaps it. Left-handed people don’t write in a direction that goes away from their bodies, unless they’re writing backwards. If she is right handed her hand should be covering the text as she writes.

    • @solarfluxman8810
      @solarfluxman8810 5 лет назад +27

      @@Lanefasts - Yes, she is behind a clear screen. But, she is not writing backwards, that would be quite difficult at the speed she writes, and it would not be pretty. She is right handed, writing behind a screen in a normal manner with her hand moving away from her as she writes. She is not blocking the text with her hand, because she is behind the screen. But, looking at her from our side of the screen, the writing would normally appear backwards. So the solution is to either place a mirror between the camera and the screen to reverse the image, or to simply reverse the left to right orientation in video editing. That's why it looks like she is using her left hand. Try it at home. It's easy to do. Just use a mirror when recording the video. My apologies to Nancy, if you were trying to keep this a secret mystery. I know you probably don't want everybody to copy your clever presentation style.

    Great lesson!!! I am glad I found your videos I never took trigonometry and high school so I have just been teaching myself by watching youtube videos and taking notes. I want to thank you for bringing up those different kinds of right triangles because the third one you drew use to make it difficult for me to understand what title was what but you cleared that up perfectly.

    For the ones who always get confuse which is which. Hypotenuse will always be the opposite of the right angle (90 grad). The adj. hence its name is located next to the theta and opp., is positioned always on the opposite side of theta

    NancyPi you are great. I love mathematics but get side tracked when on a specific subject. An example, I watched your eXplanation of sine , cosine , tangent. Clear, concise and unflappable, yet usually when I encounter these demonstrations my mind goes straight to the graphs, or wave cycle of these , excluding tan of course. I remained on subject this time throughout your demo. Thank you.
