    Nice video.
    Alternative for 10(b): Let the tangents intersect at D. By symmetry, D lies directly above C(2,-3), so D is (2,h-3) where h=DC.
    Slope of BC is tanθ = 1/3. Also ∠DBC=θ. sinθ = CB/h = (3√10)/h=1/√10, i.e. h=30, so D is (2,27).

    • @DMathAcademy
      @DMathAcademy  2 года назад

      I first identify the centre first of the tan graph
      Then I trace the period of the tan graph. It was being multiplied by anything but shifted to the righthand side by one space. That's the reason why you saw I put x-pi/4 there to represent the changes.
      Lastly I choose one of the point and substituted both the "c" and "b" I have identified to track down "a"

    Quick question: at the beginning, in question 1, when you reformulated the equation, where did you get the coefficient “-4”?, although thank you! This helps a lot.

    • @DMathAcademy
      @DMathAcademy  2 года назад

      hmmmm when you differentiate any formula, we will minus that coefficient of the variable x by 1 rite. Hence, ?x^-3 after being differentiated it will become -3?x^-4 :D
      I'm not quick sure whether the reply above is about what you were asking or not x.x you can further elaborate if it otherwise. I will reply to you asap

    • @DMathAcademy
      @DMathAcademy  2 года назад

      it depends on the circle shape that was given to you. if they used radian to represent the sector then you gotta use radian to solve the question. vice versa :D
