Trig graph memo walk-through May/June 2022

[@t.m.e8880]

Guys do questions that Malume uploads if you want to write well tomorrow more especially those who feel like giving up

[@zinhlendaba9884]

Sir you made a mistake I think at 7.5, because if the graph is at -60 and it's shifted 5 units to the right it's supposed to be -55 not -65.

[@Jurisdiva2005]

Yes it's a mistake

[@mikemike-nz2km]

i think he's right. When you shift the graph to the left you add and when you shift to the right you subtract

[@lula1626]

@@mikemike-nz2km Ya its like the opposite. when its + a value you move back and when its - a value you mave forward(to the right)

[@artntanxkunenentando6344]

Exactly my point👀too bad malume has not seen this yet💔

[@MlungisiNkosi]

Apologies guys I made an error

[@mrmashabani968]

Sir We Need Lesson Or More Question Of Trig Graphy ASAP ❤

[@sizwemajozi8598]

On the last question Isn't it supposed to be -55 instead of 65 because you're shifting by 5 degrees from - 60 too the right?

[@philanikhambula5897]

Yea i was about to ask that too

[@MlungisiNkosi]

Yeah you’re right, I made an error

[@Roxyleah]

Yeah same here I was getting confused

[@ilonahendricks4709]

Sir I think you meant 55to125 for an increasing function😁

[@katlehomphela7421]

Thank very much sir you really make our life's more easier 🙏❤️🕯️

[@buyile_beverly]

Question 7.4.2? Why isn't it negative 55 degrees? Because from negative 60 degrees to the 👉 right is negative 55 degrees?

[@AshleyVisser-ko4ig]

Yes....-55 not -65

[@vumelanii]

-55

[@karaboskariba1324]

Mr malume sir , May you please do another example where we are required to draw this graph and please show us how to get the points using our calculators

[@OnothandoNgoyi]

Mode>>table>> fill in graphs’ equation and press =. If there’s only 1 graph, ignore g(x) by pressing =.
Your starting and ending points are your interval.
For step, I usually select 90 unless it’s a tan graph, then I make it 45. I think that part depends on you, I’m not sure.
The calculator will then display the points to plot.
All the best for tomorrow’s paper❤️

[@karaboskariba1324]

@@OnothandoNgoyi Thank you very much ❤️❤️

[@feelings298]

Plz do another trig graph 🥺🥺

[@sparkle38]

How to find the turning point of trig function? I only know that we have to use first derivative is =0

[@italian_patatoe9425]

You can find the min and max Y value by the amplitude
Then use that in the equation to find the x value

[@italian_patatoe9425]

And also take into account any vertical translation

[@matselengmahlase1632]

Malume at 7.3 isn't -90 also the solution?

[@mpilenhlethembelani-ev8by]

thank you sir this was too hard for me to understand it only by my self please malume do more vedios for grade10 plzzz

[@MlungisiNkosi]

I’m glad i could help

[@VuyileNdlovu]

Sir 7.4.1 and 7.4.2 it's not suppose to be greater than as it's 🥺?

[@NtuliAntoinette]

I don't understand

[@lungatshepiso6331]

😢same applies

[@NjabuloNdawonde-g3t]

I love u sir ❤😊🙏🙏🙏

[@MlungisiNkosi]

🫂🫂🫂🫂🫂❤️

[@lula1626]

PLEASE HELP. Why is he saying 65 instead of -65?

[@MlungisiNkosi]

I made a mistake sorry

[@NolleciaMkhonto]

So sir why do we say f(x)=0 and g(x)=0?

[@karaboskariba1324]

First one Danko 🔥❤️

[@Gracekadzombe]

But if you shift the graph 5 degrees to the right from 60 wouldn't it be 55

[@MlungisiNkosi]

Think about it carefully

[@firefistace3476]

I think it's supposed to be -55
Since I was shifted to the right 5⁰

[@lifewithyanga5554]

Good afternoon Sir. May you please do questions from an IEB paper 2? 🥲🙏🏾

[@mukhethwamposhomali3750]

Malume please do another trig graph🥺😭

[@baby_kgomotso__02]

Thank you so much Sir❤❤❤❤

[@OlwamJack-fy1uh]

Did not understand 7.3

[@Gracekadzombe]

Can you do a video for introduction of graph interpretation

[@MlungisiNkosi]

Yes I will

[@Brentana]

yoh i love u sir

[@bongukuphilathobela5353]

Thank you 🙏❤️

[@roseline_mabogwane]

Thank you 🤗🤗
