Good thing math doesn't change, unlike computer science where every old video is almost useless changes 😢

I am a first year collage student who have started his degree 12 years after A'levels. Due to this huge break in formal studies I had difficulties in understanding and recalling the stuffs that I did in my A' levels. However, with the help of this brilliant tutor I have build an excellent self confidence in Mathematics and studies has never been this easy...This is brilliant....May god bless all of you who works in this

[@braixendon5496]

I got an A in my mock exam... thanks alot my friend!

[@ExamSolutions_Maths]

Excellent. I hope you can continue like that down to the exams. Best wishes.

[@braixendon5496]

ExamSolutions thanks alot my friend, I really do appreciate it

[@ExamSolutions_Maths]

Turning points are stationary points.

this is really useful thank. i'm doing further maths iGCSE and couldn't find something as clear as this anywhere else. thanks!!

You're my saviour! Couldnt find an efficuent explanation in the youtube channels i usually use. Thank you

[@nathangibbons4913]

thank you! so helpful, learned a 7 mark question in 7 mins!

I think your videos are the only reason I get good grades in maths. Great video!

Thank you and I hope they continue to give you good grades

Thank you so much, sir! You are the BEST ever maths KZbin channel and instructor!!

[@shaf621]

To those of you who do Economics at degree level, I heavily reccommend ExamSolutions as he makes the maths a lot easier, espicially on topics such as this one, fractions, statistics, exponents, algebra and integration.

[@Enoo_]

Does economic math get anymore complicated than A level math? The topics you listed are very simple at A lvl so far. And I’m considering an Econ degree

[@shaf621]

@@Enoo_ Can be, expect there to be lots of S1-2 content such as Standard Deviation, Normal Distribution but also extensions to that in Confidence Intervals and Binomial Distribution. Then with the normal maths content expect, a lot of stuff on Differentiation, Integration, Partial Derivatives, Algebraic Manipulation and Indicies.

I still can't believe how straight and nice your writing is. With a computer mouse too

i have a question and i have to find the values for x using dy/dx so i would i find values for x if y=x^1/2 - 2x and y=x +9/x?

[@davidromm3259]

How did you do the factorization cuz usually we factorize in a way called the Middle Term but what was this??

[@ExamSolutions_Maths]

It sounds like you do factorising by grouping. This method is by inspection. Look at this page.www.examsolutions.net/tutorials/factorising-quadratic-expressions/?level=A-Level&board=Edexcel&module=Pure-Maths-A-Level&topic=1172

im a bit confused are turning points the same as stationary points :S you dont have any videos on turning points :( please help!

[@imstheimee3717]

Hi. How is there a +3 and -1 inside the brackets (the fourth part) 2:52 Thank you.

[@imstheimee3717]

I don't quite understand how to do it.

[@ExamSolutions_Maths]

Inside the brackets, you need 2 integers which multiply to give -3(the c value of ax^2+bx +c), but add to give 2 (the b value of ax^2+bx +c). These integers are +3 and -1. Watch this video for more examples kzbin.info/www/bejne/f4HFe5-iZrJmr5o

[@jahanzaib_kaleem]

how does differentiating 4 give us 0 . i mean 4 is basically having a power of 1 so 1*4^1-1 . hence 4^0 which equals 1 not 0?

[@karenlau8491]

4 is a constant and any constant differentiated is equal to 0 :)

[@Daniel-sg8xt]

bruh u cant differenttiate 4 cuz there is no x value with a power therefore abracadabra its gone

[@SaadKhan-gf9ut]

Basically constant are multiplied by x to the power 0 now when we differentiate x to the power 0 the answer comes 0...

[@samgirl964]

Thankyou

[@samkolij2]

so how would u differentiate x squared + 6x?

[@ysd-xi6pe]

What?? Still searching youtube for maths help. Are the videos from 2002- Ive never heard more

[@Thre3Dawg]

YES!

[@subbuselvi2001]

how do you find stationary points if you cant differentiate directly

[@thanvirm101]

Thx sir

[@ExamSolutions_Maths]

Thanks for viewing

[@sjdude5577]

thx

[@TSMK900]

You should have went into more detail on the factorising part,never understood that part.

[@FireVortex720]

That is GCSE level factorisation, if you are doing this, you should know that by now.

[@joshuaimadeit3917]

y=-7 not -9??

[@l.jboylan6704]

WHERE DOES X-1 COME FROM

[@johnhitchon8406]

i swear -4 to the power of 0 is -1

[@ExamSolutions_Maths]

Nope, any value (apart from 0) raised to the power of 0 is 1.

[@yamin_05]

YOU DONT SAY OR WRITE DETAILS AT ALL LIKE WTF IS DIFFERENTIATE
