This is tough

[@athinilimaphi9078]

Not really

[@SalamiitAbebe]

Just do the videos more than once u will get the hang of it

[@sphethomadonsela2734]

You made me a physics Genius😸 last year Sir, and I'm still Grateful. The matrics of this year are sooo lucky since you're also doing maths videos , which means not only will they be best in Physics but also in maths❤.

[@MlungisiNkosi]

That is awesome Sphetho… Please make sure to give them the plug 😀

[@claytoncadigan8478]

Hey Mr. Nkosi well i was wondering is possible to do euclidean geometry after this lessons of functions

[@MlungisiNkosi]

I’ve started on Trig and thereafter Euclidean Geometry

[@BoitumeloMakape]

You’re the best 🤓

[@anitamazunda7857]

I was wondering if it's possible to do more examples of statistics

[@MlungisiNkosi]

I’ll do that

[@thee_selmaa2376]

Your videos really help ❤

[@lesedinkosi2343]

Do you mind answering past papers for mathematics on functions 😩

[@MlungisiNkosi]

I definitely intend on doing so

[@dipe6376]

Hello sir, are you going to do a video solely based on graph interpretation ?

[@MlungisiNkosi]

Yes I will

[@machoenekarel4968]

sir ,about the first example where you were substituting your a-value,i think you mande a mistake about the negative sine because our y-value was supposed to be -3......but you are a life saver

[@bhekisisamthokozeleni3670]

You're so helpful man.

[@MlungisiNkosi]

Thank you

[@victoriayandisa2755]

Sir please do stats,where three rows are included 🙏

[@jay-zeecloete6747]

Our favourite uncle😁❤️

[@Tyger545]

Hello sir can you please do a lesson on finding the equation of a exponential function “logarithm “

[@MlungisiNkosi]

I will do both logs and exponents

[@anitamazunda7857]

Please do statistics grade 12

[@MlungisiNkosi]

Will do

[@robertmphaka5208]

Hey Sir the second one were a is 2 b is -12 c is 16 Seems easy and fast thank you❤

[@MlungisiNkosi]

Great 😊

[@yomelelampiko2071]

Sir for the inverse of g(x). When substituting to find H(x), why did you only write 2(x) and not 2(x) -9

[@MlungisiNkosi]

Apologies for that

[@lowkey_moss]

Sir,this means that your value of k is not 0 but its 9

[@relebohilechantell7902]

Sir could you please do statistics ?🥺🙏

[@MlungisiNkosi]

I definitely will during this week

[@shes.li_melanin]

sir please do a VIDEO GIVING US TIPS AS TO HOW TO PASS MATHS

[@MlungisiNkosi]

Most definitely. Thank you for the suggestion

[@aishamadiyah9784]

Hey sir I wanted to ask if we could simplify the equation 2x^2 - 12x + 16 by 2? Or do we leave it like that?

[@MlungisiNkosi]

Yes you may divide by 2

[@nobuhlengcobo9415]

Sir can you please help us with log graphs and please use the September 2018 maths paper from question 5 to 7 iwas trying to revise with it but I failed some of the questions

[@MlungisiNkosi]

Please send me the question paper

[@shes.li_melanin]

greetings am new here and it has been awesome.Lets hope i will kill this topic and this term.Because my term 1 marks are not pleasent .
