You Are An Angel In Hard Times. Thankyou. :)

got my revision for a test tomorrow with 1.5 speed. life saver.

[samaysoni]

You really are an amazing teacher, thank you!

[mylesanthony]

nice, in holland the calculators are not permitted, so I'm glad youre showing us both ways!

[lovead]

You have explained it so well. I am so happy I found you

[SuperFerdie]

It's not difficult to prove that the maximum heights are in the inverse ratio of the standard deviations, so the Y curve is two thirds the greatest height of the X curve.

[thomasclarke]

at 8:09, u mention that the y axis is frequency density, but is it not probability density?

[adimisra]

will that formula be in formula book for edexcel

[StreamerHighlightsHQ]

for the first normal distribution, you minus and added 3
for the second normal distribution, you added 4.5
why 4.5? and why did you minus and add from the 3rd standard deviation?

[oliviagrace]

when typing in the calculator of normal pd to find the height of the curve, why is x equal to the mean?

[littricks]

Can you make videos solving CAIE questions of S1

[Zammiez]

Do we need to memorise the formula? Is it required for edexcel? Will we ever be expected to use this formula in our answers?

[joshplayz]

If I take X and transform it by X - mu, surely that is a translation to the right by mu, so why does it translate it to the left to 0?

[najukeshwala]

im confused how did you get 4.5 to take away?

[Masowe.]

i never thought the calculator can be unreliable🥲🥲🥲🤔
