    It’s a nice video, but I don’t think this is calibrating the servo, but rather adjusting your program. You can clearly see that in all those cheap servos, the range is never 180 degrees. Fixing that would be calibrating the servo.

    9:18 Quick Practice 8.14 is similar to 2.15. Only 1 question is deleted. 12:11 Quick Practice 8.15 is similar to 2.16. But part (c) is added.

    3:31 Quick Practice 8.13 is similar to 2.14. But the number changes from 9308.5 to 93085, therefore the answer is 9X10^4 + 3X10^3 + 0X10^2 + 8X10^1 + 5X10^0

  • @daisychow286
    @daisychow286 Год назад

    Quick Practice 8.8 = Quick Practice 2.9 Quick Practice 8.9 = Quick Practice 2.10. Part(b) the question changes to 10^2 and therefore the answer is -500.1 Quick Practice 8.10 = Quick Practice 2.11 Quick Practice 8.11 is not same as Quick Practice 2.12, but you can learn the skills. Quick Practice 8.12 is not same as Quick Practice 2.13, but you can learn the skills.

    It's nice. But it seems like a basic proximity sensor based closed loop system. There needs to be one authentic feedback signal involved to satisfy the condition of the user-defined passing protocol to initiate and execute the unlocking routine.

    8:31 「Ratio of length 」= 1 cm : 1.8 m 「Ratio of area 」= 1 cm2 : 3.24 m2 正如影片所說,由 長度 變做 面積,是不同的 scale。

  • @daisychow286

    Mistake made at 1:06 Left hand side is 「ratio of length 」 Right hand side is 「ratio of area 」 They are not equal after taking square and therefore 「=」should not be used.

    There are few reminders: (1) No need to name the lines. If it is not a proof, state which triangle you are using if there is more than one triangle. And then use the numbers directly. (2) Write (Pyth. Thm.) every time you use it. (3) No need to show your calculation in details. We expect you have calculator. Refer to the video on how much steps I write,

    About the last question HKCEE AM 2007: Since dy/dt is -2 only when y = 3, we cannot substitute dy/dt = -2 so early. Therefore, the steps should be When y = 3, x = 8 or -8 (rej) [先計當 y =3,x 是多少] 2x/4 (dx/dt) + 2y (dy/dt) = 0 [之後才 D] When y = 3, 2(8)/4 (dx/dt when y = 3) + 2(3)(-2) = 0 [最後才全部 sub 入去] 4 (dx/dt when y = 3) -12 = 0 dx/dt when y = 3 = 3 m/s

    1. 如果你有短暫記憶,怕有D公式唔記得的話,一開考先將你會唔記得既公式寫左係草稿先。 2. Calculator screen make sure [D] 字 (stands for degree), make sure program 入哂,記得邊條係 program 幾,識用。 3. 太緊張會影響考試,唔識做,深呼吸,先去下一條。 4. M.C. Q1~30 ABCD choices 平均,Q31~45 choices 平均,唔識可數下,選個最少既。 5. 因為疫情關係,我諗份卷會淺,人人都識既題目 請 double check make sure 無 careless mistake 無抄錯數字 先去下一行,做得快 但 抄錯數字無用。 Level 2 aim 40, level 4 aim 70, level 5 aim 80,唔一定要做哂成份卷,你做哂但有好多 careless mistakes 分數可能更低。以 level 4 為例,如果你 A1 A2 全中,B 只做 short Q or long Q part a ,已經好足夠。 當然我唔係叫大家蝸牛式慢慢做卷 然後 做唔切,我只係想強調,一些做卷常唔小心既同學 (代表人物 Alyssa 🤣),不妨每題做完都望一眼,make sure 無抄錯先去下一題。 最後就係,勤力,盡力,就無悔!DSE 加油!我賜俾大家 清醒的頭腦!精靈的眼睛!勇氣!幸運!

    9:39~10:11 The bracket means "AND". I should add back the word "when". When x = 4, y = 16. AND when x = 4^9, y = 4^6.

Dr's explanations are educational and he really helped me a lot on my finals! He is an informative med student in Europe. I recommend you see his YT out and give the Doctor a subscribe! 👉 #DrEthanOnRUclips
