Do you need more videos? I have a complete online course with way more content.

Kevin i really want to say that i appreciate you a lot. I failed matric last year and now I am going to do a rewrite. You have made me understand the work way better than any teacher and you explain everything clearly. I am so glad i found your channel in time.

Here comes a new matriculant struggling after the first day of the introduction of trigonometry 🙋‍♀️ not gonna lie, you're dope sir!!

[Siyabonga]

💐💐💐💐Take bro I won't take no for an answer.. What you are doing is beyond the word awesome we appreciate you as matriculants ♥️👏

[ntokzindaboizin]

In case ur as slow as me, I replayed last sum 6 times before kinda understanding it. Hope ur motivated😭😭😂

[banelentuli]

How do you make mathematics look so easy?
Because I would literally understand everything when you're explaining and stuff but when I decide to do a certain question I just get stuck

[esvarrstocker]

I thought the theorem of Pythagoras is a + sign. Why are you using a negative sign? 5:43 5:35

they asked something like this in trials and i just blanked out and lost such good marks TT thanks for the explanation

Sir .3sin(2A)=1 .then we decide both side by 3 ...Sin(2A)= 1/3 ..since Sin2A is a double angle we can change it into 2SinACosA... 2SinACosA=1/3 ..then we divide by 2 both sides then we left with SinACosA=1/6... we change CosA into -2{2/3 ....SinA(-2{2/3) = 1/6 we divide both sides by the value of CosA which is -2{2 /3 ...then SinA = 1/6 divide by -2{2 / 3 then we get that SinA = -{2 /8

{ REPRESENTS ROOT}
how is this approach i got SinA this way ..please correct me

[RutzBikazy]

For no 3 when u use the cos²a -sin²a it gives a different answer than the one you got

[sibongilesikhosana]

Can you please do more sums of diagrams that have a double angle or (2A) please ???

[danielkelsosmith]

But what if there’s a tan(2A) in the question?

[SisterandbrotherKT]

i just wanna say thank you very much sir you helped me a lot

1:52 Why is it -4 ? Because when you used the Pythagoras theorem it was 4

[nobuhlengcobo]

Sir since on the 3sin(2A)=1 sum it was not specified to not use a calculator is it wrong to do do it like Sin2A=1/3 2A=sin¯¹(1/3 2A= 19.4712. A=9.74. Sin(A) = sin(9.74) which is 0.167 which is the same answers with the one you gave but in a decimal format

[trequeciandlovu]

9:01 we divided by two ... so why did our 3 become a 6 ?

[ziyaadsaban]

can your answer be the decimal value instead of the fraction (last question)?
