Trigonometry Pt. 4 - Double Triangle Trig

  • This video will take the basics we've learned about sin, cos, and tan, and apply them to a slightly more complicated picture. The pictures in these problems contain multiple triangles. The reason I call them "Double Triangle" problems is because they all boil down to working with a pair of triangles in order to solve the problem.

    You answered the question I been trying to find all day. You can’t use that triangle because it’s not a right triangle. Makes sense now

    Love this video it was so helpful, but you need to slow down I had to pause it so many times to keep up

    • @RealMikeDobbs
      @RealMikeDobbs  2 роки тому

      Thanks so much- glad you found it helpful. It's always tough to decide on pacing in a video, because if it goes too slow people will turn it off and try a different one. A lot of people also won't watch a video if it's 30 minutes long, so I try to keep them under 15 to 20. To do that, I've chosen a relatively quick pace because I know you can pause it anytime you want. That's the reason I speed up the animation when I'm solving the equations. I figure you can pause if you need to while you work it out, and then just press play when you're ready. Thanks for watching and commenting 😄

    Do you think you could make an email or some sort of platform for people to send specific questions and possibly send you a picture of the problem they are solving? Thanks your videos are so helpful.

    I have officially proved my hypothesis that CBSE is making high-schoolers do math that is at least a grade above them according to British or American standards. Like, I'm in 10th grade, and I'm doing questions that are of this sort, but are thrice as hard, and then I see the comments full of high schoolers who only have to do these q's, like what?!?

    • @RealMikeDobbs

      I can understand your frustration as a student, feeling like you have to do harder work than other students. The truth is though, the harder the content that you challenge, the more you will get out of it. It’s like going to the gym. If you just lift very light weights you aren’t going to get the benefit you would if you really challenged yourself; try to think of it like that 😀

    Can you do the same topic with isosceles triangle and bottom length?

    • @RealMikeDobbs
      @RealMikeDobbs  2 роки тому +2

      Hey- thanks for watching 😄
      I'm not entirely sure what you mean about Isosceles triangles. I can't think of any specific relationship in Isosceles triangles regarding the bottom (base?) length. The only thing I can think of is maybe Isosceles right triangles? Those are special, and I have an entire video on those and 30-60-90 triangles. Maybe this will help you out? ua-cam.com/video/hftTj9RfuxM/v-deo.html

      @@RealMikeDobbs ok thanks what I mean is that like it's an isosceles triangle then it has an angle in the first triangle with a length at the bottom. But thanks anyway.

    Hello! I noticed you stored some numbers in your calculator as A and B would you mind sharing how to do that on a calculator? I have a Casio fx-300ES PLUS

    • @RealMikeDobbs
      @RealMikeDobbs  9 місяців тому

      I’m sorry, I’m not familiar with that calculator. If you google the manual you should be able to find how to do it, or search UA-cam for a video.

    6:29 why is 17 and 50 put togather?

    • @RealMikeDobbs
      @RealMikeDobbs  3 місяці тому

      If you watch the video from 6:29 I explain what's going on. The top right angle in the larger triangle is made up of the two smaller angles (17 and 50). So, you need to add those together to get the angle in the large triangle (the one I draw separately in blue)

  • @prosperkalu1270
    @prosperkalu1270 Рік тому

    what if we don't know one of the angle , how do we calculate it

    • @RealMikeDobbs
      @RealMikeDobbs  Рік тому +1

      I'm not sure what you're asking. There's a minimum amount of information needed to calculate missing parts of a triangle, and there are multiple different methods available depending on the information that has been provided. If you are looking at a problem that's different from the ones in this video you may want to check out some of my other trig videos on Sin, Cos, Tan, as well as Law of Sines. There's also the law of Cosines, but I don't think I have a video on that one yet.
