king's theorem

最尾果條將(x-2)變做(x+1-3)快好多

Thank-you, this is very interesting. I study descriptive geometry through orthographic projection. You say that line AB is perpendicular to any line in plane pi. Should we clarify this statement by saying that AB is perpendicular to any line in plane pi that passes through point B, the foot of the perpendicular from A ? We cannot say that AB is perpendicular to any line in plane pi that does not pass through point B can we?

Thankss❤

Q15: y= 256x^(-8/3)

Thx

how to calculate modulus with FX-50FH?

lower quartile=14 upper quartile=16 inter-quartile range=16-14=2

👍👍

😂

其實咁簡單既題目應該教返正確步驟唔應該教代數

hi , can i have a formula of solving the equation with only one unknown ?

2002，我改左part b 少少，太經典了

無記錯係2003 pure pp 題目

Thanks!

老師你好，請問題目中給定VC 垂直plane ABC代表什麼意思？

In the last question, x ≠ 1

Q(13)(a) 要唔要解釋埋x-intercept 或 y-intercept不相同，所以沒有相交點？

16:42 7b Let x = y^nm

1(k) the answer should be 3(2x+7)[sin(x²+7x)]^(1/2)cos(x²+7x)/2

20:23 The red part should be -1/2x^(3/2) 26:07 f(t) = 2t^2+2/t^2+12 f'(t) = 4t -4/t^3 f'(1/2) = 4(1/2)-4/(1/2)^3 = 2 - 32 = - 30

30:00 Should be 800

03:07 The answer should be -2

Q3(b) Should be 106240

❤

Mr Lo又靚仔心地又好，多謝哂 但係我炒咗😢

盧sir 我愛死你 希望今次ut可以攞到好成績！

LOWI sir 又靚仔有好人🎉 必須合格😂

Mr Lo 又靚仔心地又好 多謝晒❤️ 最可惜我份卷冇滿分 得90幾%

Hi❤❤❤

(v). ln((1-sqrt5)/2 need reject

15:07 Q54 update: surface area of R =(2x+3)(x-1) =2x² - 2x +3x - 3 =2x² +x - 3

勾起我兒時回憶，當時冇電腦，連計算機都用來寫 progam

More m2thx

14:30 the first class mark should be 90.5, not 80.5.

20:43 theta = 90 degrees should be rejected 32:41 x/2=210 degrees

. d f '(x) Note that ------- ln [ f(x)] = ---------- dx f(x)

how do you find the iqr on it ? thankyou

33:29 It should be 3^-8, not 3^-10 33:54 It should be 354292/9, not 354292 39:30 The answer is 24532

最後（bi）個題perimeter 應該係2（p+q)=m

why dont use sum of root and product of root

Sir you are the best I am TZEUTONG darielle F3a thank sir
