    As for someone who's taking physics without pre-calc, radicals are Greek.

      I am so sorry dude. This is my bread and butter. I loved it in high school. I loved it in university. And i love it in my current job.
      I am back for a refresh! after so many year. This mans voice is of an angel.
      Please keep doing examples. The more you practise, it will become second nature. Just like everything else in life.
      God speed.

    When I do the practice problems on the site, the x and y values are mixed up for some reason. One time, the opposite side of the of the triangle was done as the x axis somehow. I'm doing the calculations right, but I cannot tell if the site is doing it wrong or if I am. Most likely I am.

    the tail and the arrow were wrong
    two arrows never meet each other it's always tail to arrow and vice-versa

    • @brandrixco6246
      @brandrixco6246 6 років тому

      Why is it false? When you do vector addition both a and b always meet arrow to arrow to form c. |

    PLEASE, *stop* repeating yourself. You said "might look something like" 3 times, and I know you are trying to stray away from dead air, but it is really grating on the ears to listen to somebody repeat themself this many times, and in a set of videos that hundreds of students are forced to listen to for school, it is not acceptable to be doing something this infuriating. Fix this.

      Yes thank you i had to keep pausing the video to stop getting annoyed...its okay if theres a bit of silence in the vid but hearing the same thing over and over is so frustrating

    • @miesht430
      @miesht430 6 років тому

      as students, if this is the type of explanation that helps us, we have the right to ask for an easy to follow video, not something that frustrates us on top of our already stressed minds...especially from khan academy they usually produce great content
