2018 GCE Paper 2, Question 1-3

[davidkadobi]

on the inverse the adjoints are not swapped when multiplying by half sir. The 4 was supposed to be swapped with a 2

[LovelyMutukwa-jygb]

You teach very good sir, I understand your teachings very much

[WilsonChulu-edjb]

Hello there Sir it's me Wilson watching from Lusaka chamba valley loving your teaching

[venaliciousmanga]

I don't know whether I'm the one who's confused or? But in the first question by finding the inverse of A. You didn't exchange the numbers in the main diagonal but you gave the 2 and 3 their negative numbers. Please help 😢

[MwakaKambunga-ww]

You teach very good sir, I'll continue to follow you ❤

[SusanMusa-yb]

Finding the inverse is all about changing the diagonal

[OsmanIYKamara]

Did well but the major diagonal was not interchange why

[SambaBanda]

Sir can you leave the inverse without multiplying

[TheIT_Classroom]

Please check the entries in the leading diagonal.

[PatrickMwansa-iipg]

boss sorry you did not interchange the leading diagonals for the adjoint to find the inverse

[LovenessMwitwa-ld]

I will pass with flying colors bcoz of u
