Sir, thank you so much! It helps me a lot. May God bless you

[@nabihaali506]

Sir at 52:39 I did 2500/x +15= 2500/x+20 but I reached the equation through this so is it also correct?

[@irfanbhatti5384]

love u bro helped me alot 👊👍

[@OALevelMathematics]

Glad to hear that

In 45:46 why you didn't include base area ??

[@moinhassan6500]

would 360 be used in every kind of quadiletral ?

question 6 part c

[@wolfalwaysanonymous6490]

Yes every 4 sided quad

Thanks King❤️❤️

32:13 whyd u multiply it with 3??

[@MashalBaloch-se1jv]

you are really good teacher but at 38:57 you forgot to draw a point which is

[@humayunraja5585]

41:12 the tangents value is wrong as per the ms U missed the points (1.5,0.5) ig that's why

[@OALevelMathematics]

I don't actually check everything. But if you understand and know how to get to the right answer, I am happy.

[@ucifertm1196]

Nice keep it up💯

[@OALevelMathematics]

Thanks 💯

[@raahimabbas1757]

how and why did you do the ratio of the area and volume in question 8's d) i) ?????? do you have another method for these types of questions???

[@OALevelMathematics]

I explained in the video. There is no another method. You have to use Similarity - ratio for this question.

[@randomshit1673]

sir i am not understanding these graphs of functions questions. could you please guide me to a tutorial explaining that topic

Is it for Math D or Add Math?

i tried finding angle CBA of question 3 by using the cosine rule. Can someone plz tell me why this is wrong?

[@OALevelMathematics]

I tried Cosine rule as well, and it works. should give the same answer.

dont forget to solve it according to DMAS rue

Why can't we take coordinates (4,-3) to find the equation of line in Q7(a)(i)

[@abdullahkaleem1250]

we can it is totally our choice as it makes no difference

[@tayabaali6270]

In Q 6c) can't we add all the angles 131 +65+ 57= 253 and then take upper bound of 253? 359.5-253.5= 106?

[@OALevelMathematics]

Mathematics is logical, there are many methods you can use to get to the answer. If your method makes sense to you, then you can use it

[@tayabaali6270]

@@OALevelMathematics but the method that im mentioning here, answer isn't the same in marking scheme. What's wrong with method?

[@dragonemperor5728]

There is one error you did. You should take upper bound of every angle given then subtract it from 360 degree.

[@dragonemperor5728]

@@tayabaali6270 There is one error you did. You should take upper bound of every angle given then subtract it from 360 degree. When we deal with questions regarding u.b and l.b the u.b or l.b should be used to find answer depending on question.

hello...no.11 part (b)(iv) - must be 7.37power 2 instead of 7.32 power 2.
